    0. Linux统计文件夹下的文件数目

    统计当前目录下文件的个数(不包括目录): ls -l | grep "^-" | wc -l 

    统计当前目录下文件的个数(包括子目录): ls -lR| grep "^-" | wc -l 

    查看某目录下文件夹(目录)的个数(包括子目录): ls -lR | grep "^d" | wc -l 

    命令解析:

    • ls -l     长列表输出该目录下文件信息(注意这里的文件是指目录、链接、设备文件等),每一行对应一个文件或目录,ls -lR是列出所有文件,包括子目录。
    • grep "^-"  过滤ls的输出信息,只保留一般文件,只保留目录是grep "^d"
    • wc -l     统计输出信息的行数,统计结果就是输出信息的行数,一行信息对应一个文件,所以就是文件的个数。

    3. GPU 和 CPU 数据之间的转换:

      (1)CPU --->  GPU:   a.cuda() 

      (2)GPU ---> CPU:    a.cpu() 

      (3) torch.tensor --->  numpy array: 

        a_numpy_style = a.numpy() 

      (4)numpy array ---> torch.tensor: 

     1 >>> import numpy as np
     2 >>> a = np.ones(5)
     3 >>> b = torch.from_numpy(a)
     4 >>> np.add(a, 1, out=a)

    4. Variable and Tensor: 

      ==>> programs occured error:

      expected a Variable, but got a Float.Tensor(), ~~~~ 

      ==>> this can be solved by adding: 

    from torch.autograd import Variable 
    hard_neg_differ_ = Variable(hard_neg_differ_) 

      ==>> this will change the hard_neg_differ_ into a variable, not a Float.Tensor() any more. 

      we can read this reference: http://blog.csdn.net/shudaqi2010/article/details/54880748 

      it tell us: 

     

    >>> import torch

    >>> x
    
    (0 ,.,.) =

      But, you can not directly convert the Variable to numpy() or something else. You can load the values in the Variable and convert to numpy() through: 

      value = varable.data.numpy().

     

    5.  Some Operations about tensor. obtained from blog: http://www.cnblogs.com/huangshiyu13/p/6672828.html 

    ============改变数组的维度==================
    已知reshape函数可以有一维数组形成多维数组
    ravel函数可以展平数组
    b.ravel()
    flatten()函数也可以实现同样的功能
    区别:ravel只提供视图view,而flatten分配内存存储
    
    重塑:
    
    用元祖设置维度
    >>> b.shape=(4,2,3)
    >>> b
    array([[ 0, 1, 2],
            [ 3, 4, 5],
    
           [ 6, 7, 8],
            [ 9, 10, 11],
    
           [12, 13, 14],
            [15, 16, 17],
    
           [18, 19, 20],
            [21, 22, 23]])
    
    转置:
    >>> b
    array([0, 1],
           [2, 3])
    >>> b.transpose()
    array([0, 2],
           [1, 3])
    
    =============数组的组合==============
    >>> a
    array([0, 1, 2],
           [3, 4, 5],
           [6, 7, 8])
    >>> b = a*2
    >>> b
    array([ 0, 2, 4],
           [ 6, 8, 10],
           [12, 14, 16])
    
    1.水平组合
    >>> np.hstack((a,b))
    array([ 0, 1, 2, 0, 2, 4],
           [ 3, 4, 5, 6, 8, 10],
           [ 6, 7, 8, 12, 14, 16])
    >>> np.concatenate((a,b),axis=1)
    array([ 0, 1, 2, 0, 2, 4],
           [ 3, 4, 5, 6, 8, 10],
           [ 6, 7, 8, 12, 14, 16])
    
    2.垂直组合
    >>> np.vstack((a,b))
    array([ 0, 1, 2],
           [ 3, 4, 5],
           [ 6, 7, 8],
           [ 0, 2, 4],
           [ 6, 8, 10],
           [12, 14, 16])
    >>> np.concatenate((a,b),axis=0)
    array([ 0, 1, 2],
           [ 3, 4, 5],
           [ 6, 7, 8],
           [ 0, 2, 4],
           [ 6, 8, 10],
           [12, 14, 16])
    
    3.深度组合:沿着纵轴方向组合
    >>> np.dstack((a,b))
    array([[ 0, 0],
            [ 1, 2],
            [ 2, 4],
    
           [ 3, 6],
            [ 4, 8],
            [ 5, 10],
    
           [ 6, 12],
            [ 7, 14],
            [ 8, 16]])
    
    4.列组合column_stack()
    一维数组:按列方向组合
    二维数组:同hstack一样
    
    5.行组合row_stack()
    以为数组:按行方向组合
    二维数组:和vstack一样
    
    6.==用来比较两个数组
    >>> a==b
    array([ True, False, False],
           [False, False, False],
           [False, False, False], dtype=bool)
    #True那个因为都是0啊
    
    ==================数组的分割===============
    >>> a
    array([0, 1, 2],
           [3, 4, 5],
           [6, 7, 8])
    >>> b = a*2
    >>> b
    array([ 0, 2, 4],
           [ 6, 8, 10],
           [12, 14, 16])
    
    1.水平分割(难道不是垂直分割???)
    >>> np.hsplit(a,3)
    [array([0],
           [3],
           [6]),
     array([1],
           [4],
           [7]), 
    array([2],
           [5],
           [8])]
    split(a,3,axis=1)同理达到目的
    
    2.垂直分割
    >>> np.vsplit(a,3)
    [array([0, 1, 2]), array([3, 4, 5]), array([6, 7, 8])]
    
    split(a,3,axis=0)同理达到目的
    
    3.深度分割
    某三维数组:::
    >>> d = np.arange(27).reshape(3,3,3)
    >>> d
    array([[ 0, 1, 2],
            [ 3, 4, 5],
            [ 6, 7, 8],
    
           [ 9, 10, 11],
            [12, 13, 14],
            [15, 16, 17],
    
           [18, 19, 20],
            [21, 22, 23],
            [24, 25, 26]])
    
    深度分割后(即按照深度的方向分割)
    注意:dsplite只对3维以上数组起作用
    raise ValueError('dsplit only works on arrays of 3 or more dimensions')
    ValueError: dsplit only works on arrays of 3 or more dimensions
    
    >>> np.dsplit(d,3)
    [array([[ 0],
            [ 3],
            [ 6],
    
           [ 9],
            [12],
            [15],
    
           [18],
            [21],
            [24]]), array([[ 1],
            [ 4],
            [ 7],
    
           [10],
            [13],
            [16],
    
           [19],
            [22],
            [25]]), array([[ 2],
            [ 5],
            [ 8],
    
           [11],
            [14],

           [20],
            [23],
            [26]])]
    
    ===================数组的属性=================
    >>> a.shape #数组维度
    (3, 3)
    >>> a.dtype #元素类型
    dtype('int32')
    >>> a.size #数组元素个数
    9
    >>> a.itemsize #元素占用字节数
    4
    >>> a.nbytes #整个数组占用存储空间=itemsize*size
    36
    >>> a.T #转置=transpose

     6. image paste using python: 

    im = Image.open('/home/wangxiao/Pictures/9c1147d3gy1fjuyywz23sj20dl09u3yw.jpg') box = (100,100,500,500)
    region = im.crop(box) 
    im.paste(region,(100,70))  
    im.show() 

      

     7. pytorch save checkpoints 

    torch.save(model.state_dict(), filename)
    

     

    8. install python3.5 on ubuntu system:

    sudo add-apt-repository ppa:fkrull/deadsnakes
    sudo apt-get update
    sudo apt-get install python3.5
    

    when testing, just type: python3.5   

     

    9. load imge to tensor & save tensor data to image files. 

    def tensor_load_rgbimage(filename, size=None, scale=None):
        img = Image.open(filename)
        if size is not None:
            img = img.resize((size, size), Image.ANTIALIAS)
        elif scale is not None:
            img = img.resize((int(img.size[0] / scale), int(img.size[1] / scale)), Image.ANTIALIAS)
        img = np.array(img).transpose(2, 0, 1)
        img = torch.from_numpy(img).float()
        return img
    
    
    def tensor_save_rgbimage(tensor, filename, cuda=False):
        if cuda:
            img = tensor.clone().cpu().clamp(0, 255).numpy()
        else:
            img = tensor.clone().clamp(0, 255).numpy()
        img = img.transpose(1, 2, 0).astype('uint8')
        img = Image.fromarray(img)
        img.save(filename)

    ==>> follow the solution from this link

    To reduce memory usage, during the .backward() call, all the intermediary results are deleted when they are not needed anymore.

    Hence if you try to call .backward() again, the intermediary results don’t exist and the backward pass cannot be performed (and you get the error you see).

    You can call .backward(retain_graph=True) to make a backward pass that will not delete intermediary results, and so you will be able to call .backward() again.

    All but the last call to backward should have the retain_graph=True option.

    29. Deep copy with "clone" operation 

    A29: vis_feat = x.data.clone() 

     

    30. How to Train the Deep Network with Multi-GPU in one machine ? 

    A30: Here is a Code example from: https://www.jianshu.com/p/b366cad90a6c ( 但是这个代码不能直接跑,因为他只是一个案例,而且有语法错误之类的)。

    PyTorch 官方文档给出的接口代码 torch.nn.DataParallel 的解释如下:https://pytorch.org/docs/0.4.1/nn.html#dataparallel 

    >>> net = torch.nn.DataParallel(model, device_ids=[0, 1, 2])
    >>> output = net(input_var) 

    但是有时候想直接运行,还是不行的,比如我(T_T)。我定义的模型中包含了 RoI 的相关操作,该操作原本的调用方式是:

    align_h = model.roi_align_model.aligned_height 

    这个时候,必须改为: align_h = model.module.roi_align_model.aligned_height ,区别就是:中间加一个 module 作为过度才可以。

     

    另外一个 bug 是:原本可以正常执行的代码,加了并行化的模块后,不行了。比如:

    ==== Start Cycle 0 ====
    Traceback (most recent call last):
    File "train_lang_coAttention_MultiGPU_version.py", line 311, in <module>
    train_mdnet()
    File "train_lang_coAttention_MultiGPU_version.py", line 182, in train_mdnet
    cur_feat_map = model(cur_scene, language, k, out_layer='conv3')
    File "/usr/local/lib/python2.7/dist-packages/torch/nn/modules/module.py", line 477, in __call__
    result = self.forward(*input, **kwargs)
    File "/usr/local/lib/python2.7/dist-packages/torch/nn/parallel/data_parallel.py", line 123, in forward
    outputs = self.parallel_apply(replicas, inputs, kwargs)
    File "/usr/local/lib/python2.7/dist-packages/torch/nn/parallel/data_parallel.py", line 133, in parallel_apply
    return parallel_apply(replicas, inputs, kwargs, self.device_ids[:len(replicas)])
    File "/usr/local/lib/python2.7/dist-packages/torch/nn/parallel/parallel_apply.py", line 77, in parallel_apply
    raise output
    TypeError: forward() takes at least 3 arguments (2 given)

    这里,提示我仅仅给了 2 个参数。但是不加这个模块,是可以正常运行的。这是不是说明了,某些 bug 的存在导致了该错误?那么,是什么 bug 呢???

    Q36.  在使用 PyTorch 训练的过程中,显存占用越来越大,最终导致 out-of-memory?

     

    A36. 导致这种情况的一个可能的原因是(我自己遇到的):在计算 total loss 的时候,不能直接相加。要用  .data[0] 将数据取出来,才可以。不然,pyTorch 会自动将该部分加入计算图,导致显存占用越来越多,最终爆掉了。

     

     

    Q37. *** RuntimeError: _sigmoid_forward_out is not implemented for type torch.cuda.LongTensor

    A37. So, how to transform the torch.cuda.LongTensor style into the torch.cuda.FloatTensor ?  Try this: 

    maxIoU = maxIoU.type(torch.cuda.FloatTensor)

     

    Q38.   File "training_demo.py", line 236, in <module>
       main(args)
     File "training_demo.py", line 218, in main
       L2_loss.backward()
     File "/home/wangxiao/anaconda2/envs/pygoturn/lib/python3.7/site-packages/torch/tensor.py", line 102, in backward
       torch.autograd.backward(self, gradient, retain_graph, create_graph)
     File "/home/wangxiao/anaconda2/envs/pygoturn/lib/python3.7/site-packages/torch/autograd/__init__.py", line 90, in backward
       allow_unreachable=True)  # allow_unreachable flag
    RuntimeError: element 0 of tensors does not require grad and does not have a grad_fn

    A38. First, you need to do: from torch.autograd import Variable, then, add this line before the backward function: 

    L2_loss = Variable(L2_loss, requires_grad = True) 

     

    Q39. ImportError: cannot import name 'imresize' from 'scipy.misc' (/home/wangxiao/anaconda3/envs/goturn2.0/lib/python3.7/site-packages/scipy/misc/__init__.py) 

    A39. https://stackoverflow.com/questions/48923151/importing-image-to-python-cannot-import-name-imread?noredirect=1&lq=1 

    pip install Pillow

    pip install scipy==1.1.0 

     

    Q40. ImportError: libcudart.so.10.1: cannot open shared object file: No such file or directory 

    A40. https://github.com/tensorflow/tensorflow/issues/26182 

    conda install cudatoolkit
    conda install cudnn 

    Q41. ImportError: ./modules/roi_align/roi_align_cuda.cpython-37m-x86_64-linux-gnu.so: undefined symbol: _ZN2at19UndefinedTensorImpl10_singletonE 

    A41. First, you need to remove the folder "build", generated from previous version. Then make this file again: 

    rm -rf build/ 

    python setup.py build_ext --inplace 

     

    Shit, aforementioned solutions can not handle the following issues: 

    ImportError: ./modules/roi_align/roi_align_cuda.cpython-37m-x86_64-linux-gnu.so: undefined symbol: _ZN3c105ErrorC1ENS_14SourceLocationERKSs. 

    Try this: conda install pytorch torchvision cudatoolkit=10.0 -c pytorch

     

    Q42. Segmentation fault (core dumped) 

    A42. This maybe caused by you forget to transform the data into GPU. Find the line the bug occurred, and do this: feature = feature.cuda() 

     

    Q43. Set edge color with PIL for visualization (RGB(0,153,255), #0099FF颜色查询): 

    A43. https://www.fontke.com/tool/rgb/0099ff/ 

     

    Q44.

    Q47. 

    from torchvision import _C

    ImportError: libcudart.so.9.0: cannot open shared object file: No such file or directory 

    A47. pip install torchvision==0.2.2 will be ok.  

    Q48. ImportError: libmkl_rt.so: cannot open shared object file: No such file or directory 

    A48. First, you need to locate the lib files by: 

    # locate libmkl_rt.so 

    /home/wangxiao/anaconda3/lib/libmkl_rt.so
    /home/wangxiao/anaconda3/pkgs/mkl-2018.0.2-1/lib/libmkl_rt.so
    /home/wangxiao/miniconda3/envs/GlobalTrack/lib/libmkl_rt.so
    /home/wangxiao/miniconda3/envs/TrackingNet/lib/libmkl_rt.so
    /home/wangxiao/miniconda3/envs/aaai/lib/libmkl_rt.so
    /home/wangxiao/miniconda3/envs/beamtracker/lib/libmkl_rt.so
    /home/wangxiao/miniconda3/envs/goturn2.0/lib/libmkl_rt.so
    /home/wangxiao/miniconda3/envs/pysot/lib/libmkl_rt.so
    /home/wangxiao/miniconda3/envs/rtmdnet/lib/libmkl_rt.so
    /home/wangxiao/miniconda3/envs/sint3.0/lib/libmkl_rt.so
    /home/wangxiao/miniconda3/lib/libmkl_rt.so
    /home/wangxiao/miniconda3/pkgs/mkl-2019.4-243/lib/libmkl_rt.so 

    Then, you can execute following: 

    export LD_LIBRARY_PATH=/home/wangxiao/anaconda3/pkgs/mkl-2018.0.2-1/lib/:$LD_LIBRARY_PATH 

    Then, this problem can be solved.

    A49. This error can't be solved by simply: pip install six. I tried this: conda install -c intel mkl-service 

    Q50. 使用conda install安装软件遇到如下错误:  Segmentation fault (core dumped) 

    2013053-c10dd7fb85bbc691.png

    通过检索,发现可能是之前安装的时候网络不良导致中途出错,于是有些包虽然在本地缓存了,但其实不完整。

    解决方法: conda clean -a 删除所有缓存即可. from: https://blog.csdn.net/u012110870/article/details/103800701 

    Q51. 生成一组随机数:

    A51. Source: https://blog.csdn.net/u014182497/article/details/80733202 

    简单的随机数据

    rand(d0, d1, ..., dn)

    随机值

    >>> np.random.rand(3,2)
    array([[ 0.14022471,  0.96360618],  #random
           [ 0.37601032,  0.25528411],  #random
           [ 0.49313049,  0.94909878]]) #random

    randn(d0, d1, ..., dn)

    返回一个样本,具有标准正态分布。

    Notes

    For random samples from 技术分享, use:

    sigma * np.random.randn(...) + mu

    Examples

    >>> np.random.randn()
    2.1923875335537315 #random

    Two-by-four array of samples from N(3, 6.25):

    >>> 2.5 * np.random.randn(2, 4) + 3
    array([[-4.49401501,  4.00950034, -1.81814867,  7.29718677],  #random
           [ 0.39924804,  4.68456316,  4.99394529,  4.84057254]]) #random

    randint(low[, high, size])

    返回随机的整数,位于半开区间 [low, high)。

    >>> np.random.randint(2, size=10)
    array([1, 0, 0, 0, 1, 1, 0, 0, 1, 0])
    >>> np.random.randint(1, size=10)
    array([0, 0, 0, 0, 0, 0, 0, 0, 0, 0])

    Generate a 2 x 4 array of ints between 0 and 4, inclusive:

    >>> np.random.randint(5, size=(2, 4))
    array([[4, 0, 2, 1],
           [3, 2, 2, 0]])

    random_integers(low[, high, size])

    返回随机的整数,位于闭区间 [low, high]。

    Notes

    To sample from N evenly spaced floating-point numbers between a and b, use:

    a + (b - a) * (np.random.random_integers(N) - 1) / (N - 1.)

    Examples

    >>> np.random.random_integers(5)
    4
    >>> type(np.random.random_integers(5))
    <type ‘int‘>
    >>> np.random.random_integers(5, size=(3.,2.))
    array([[5, 4],
           [3, 3],
           [4, 5]])

    Choose five random numbers from the set of five evenly-spaced numbers between 0 and 2.5, inclusive (i.e., from the set):

    >>> 2.5 * (np.random.random_integers(5, size=(5,)) - 1) / 4.
    array([ 0.625,  1.25 ,  0.625,  0.625,  2.5  ])

    Roll two six sided dice 1000 times and sum the results:

    >>> d1 = np.random.random_integers(1, 6, 1000)
    >>> d2 = np.random.random_integers(1, 6, 1000)
    >>> dsums = d1 + d2

    Display results as a histogram:

    >>> import matplotlib.pyplot as plt
    >>> count, bins, ignored = plt.hist(dsums, 11, normed=True)
    >>> plt.show()

    random_sample([size])

    返回随机的浮点数,在半开区间 [0.0, 1.0)。

    To sample multiply the output of random_sample by (b-a) and add a:

    (b - a) * random_sample() + a

    Examples

    >>> np.random.random_sample()
    0.47108547995356098
    >>> type(np.random.random_sample())
    <type ‘float‘>
    >>> np.random.random_sample((5,))
    array([ 0.30220482,  0.86820401,  0.1654503 ,  0.11659149,  0.54323428])

    Three-by-two array of random numbers from [-5, 0):

    >>> 5 * np.random.random_sample((3, 2)) - 5
    array([[-3.99149989, -0.52338984],
           [-2.99091858, -0.79479508],
           [-1.23204345, -1.75224494]])

    random([size])

    返回随机的浮点数,在半开区间 [0.0, 1.0)。

    (官网例子与random_sample完全一样)

    ranf([size])

    返回随机的浮点数,在半开区间 [0.0, 1.0)。

    (官网例子与random_sample完全一样)

    sample([size])

    返回随机的浮点数,在半开区间 [0.0, 1.0)。

    (官网例子与random_sample完全一样)

    choice(a[, size, replace, p])

    生成一个随机样本,从一个给定的一维数组

    Examples

    Generate a uniform random sample from np.arange(5) of size 3:

    >>> np.random.choice(5, 3)
    array([0, 3, 4])
    >>> #This is equivalent to np.random.randint(0,5,3)

    Generate a non-uniform random sample from np.arange(5) of size 3:

    >>> np.random.choice(5, 3, p=[0.1, 0, 0.3, 0.6, 0])
    array([3, 3, 0])

    Generate a uniform random sample from np.arange(5) of size 3 without replacement:

    >>> np.random.choice(5, 3, replace=False)
    array([3,1,0])
    >>> #This is equivalent to np.random.permutation(np.arange(5))[:3]

    Generate a non-uniform random sample from np.arange(5) of size 3 without replacement:

    >>> np.random.choice(5, 3, replace=False, p=[0.1, 0, 0.3, 0.6, 0])
    array([2, 3, 0])

    Any of the above can be repeated with an arbitrary array-like instead of just integers. For instance:

    >>> aa_milne_arr = [‘pooh‘, ‘rabbit‘, ‘piglet‘, ‘Christopher‘]
    >>> np.random.choice(aa_milne_arr, 5, p=[0.5, 0.1, 0.1, 0.3])
    array([‘pooh‘, ‘pooh‘, ‘pooh‘, ‘Christopher‘, ‘piglet‘],
          dtype=‘|S11‘)

    bytes(length)

    返回随机字节。

    >>> np.random.bytes(10)
    ‘ ehx85x022SZxbfxa4‘ #random

    排列

    shuffle(x)

    现场修改序列,改变自身内容。(类似洗牌,打乱顺序)

    >>> arr = np.arange(10)
    >>> np.random.shuffle(arr)
    >>> arr
    [1 7 5 2 9 4 3 6 0 8]

    This function only shuffles the array along the first index of a multi-dimensional array:

    >>> arr = np.arange(9).reshape((3, 3))
    >>> np.random.shuffle(arr)
    >>> arr
    array([[3, 4, 5],
           [6, 7, 8],
           [0, 1, 2]])

    permutation(x)

    返回一个随机排列

    >>> np.random.permutation(10)
    array([1, 7, 4, 3, 0, 9, 2, 5, 8, 6])
    >>> np.random.permutation([1, 4, 9, 12, 15])
    array([15,  1,  9,  4, 12])
    >>> arr = np.arange(9).reshape((3, 3))
    >>> np.random.permutation(arr)
    array([[6, 7, 8],
           [0, 1, 2],
           [3, 4, 5]])

    where 技术分享 is the mean and 技术分享 the standard deviation. The square of the standard deviation, 技术分享, is called the variance.

    The function has its peak at the mean, and its “spread” increases with the standard deviation (the function reaches 0.607 times its maximum at 技术分享 and 技术分享 [R217]).

    Examples

    Draw samples from the distribution:

    >>> mu, sigma = 0, 0.1 # mean and standard deviation
    >>> s = np.random.normal(mu, sigma, 1000)

    Verify the mean and the variance:

    >>> abs(mu - np.mean(s)) < 0.01
    True
    >>> abs(sigma - np.std(s, ddof=1)) < 0.01
    True

    Display the histogram of the samples, along with the probability density function:

    >>> import matplotlib.pyplot as plt
    >>> count, bins, ignored = plt.hist(s, 30, normed=True)
    >>> plt.plot(bins, 1/(sigma * np.sqrt(2 * np.pi)) *
    ...                np.exp( - (bins - mu)**2 / (2 * sigma**2) ),
    ...          linewidth=2, color=‘r‘)
    >>> plt.show()
