1.官方的
官方的按照安装流程很容易安装，只是我的环境是ubuntu16.04+cuda8，所以一直用的pytorch1.0.1（py3.7）的。也可以跑起来.但是训练的模型推理预测出来全是空啊，txt全是空的，visualize文件夹图片灰蒙蒙的没有框。loss不收敛

用ic15数据集训练也是如此，不知道问题出在哪里。后面再看看
有一个bug，是学习率一开始都是0.07，设置都没有用，需要到DB/DB-master/training/learning_rate.py这里改，被写死了
因为怀疑是版本原因导致不收敛什么的，于是我就把自己电脑上装两个cuda，8和10，装10，然后创建虚拟环境，然后又报错，报cuda错误，
error in : invalid device function
RuntimeError: copy_if failed to synchronize: device-side assert triggered
搞了好久，无解，然后解决问题的时候发现conda安装的cuda是10.1版本的，而我本地是10.0版本的，同时看到
作者在回答issue的时候说：https://github.com/MhLiao/DB/issues/36
‘
Make sure your CUDA path of $CUDA_HOME is the same version as your CUDA in PyTorch by the command of echo $CUDA_HOME. If not, you need to change the $CUDA_HOME by export CUDA_HOME=path-of-another-version or re-install PyTorch with the same CUDA version as in CUDA_HOME.
’
本地与conda的cuda版本需要一致。然后我重来一遍：
conda install numpy=1.17.4 pytorch=1.3 torchvision cudatoolkit=10.0.130 -c pytorch
如此，可以！
但是，好像还不收敛啊。。。。………………。6……6…………-%4$
2.非官方的
安装安装流程，一股脑的安装，确实可以跑，但是一开始显示， DBNet.pytorch INFO: train with device cpu and pytorch 1.3.0
因为我电脑上没有1.3需要的cuda10，所以就跑cpu了。很慢。
后来在群里看到有人用pytorch1.1.0版本编过了，但是他是cuda10.我也安装1.1.0版本，然后训练各种报错啊，无助。。。后来都放弃了，后来又重捣鼓。
在此过程中，越来越觉得anconda很好，在虚拟环境下，敲conda list可以显示安装的各个库的版本。

安装软件直接：pip install tensorboardX==1.8
不加版本号默认装最新的。
还可以pip install 'tensorboardX<1.9'.安装小于1.9版本。
主要有两个错误：

看样子好像是tensorboardX版本不对，百度一下果真，说要把版本整到1.8.conda list显示我是1.9，然后敲：
pip install tensorboardX1.8，显示如下：
Requirement already satisfied: six in /data_1/Yang/software_install/Anaconda1105/envs/dbnet/lib/python3.6/site-packages (from tensorboardX1.8) (1.13.0)

Installing collected packages: tensorboardX
Found existing installation: tensorboardX 1.9
Uninstalling tensorboardX-1.9:

直接会自动卸载1.9装1.8
然后再训练，果真只剩下最后的那个错误。

在github上面有人解答了这个问题，https://github.com/WenmuZhou/DBNet.pytorch/issues/4
在DBNet.pytorch-master/data_loader/init.py， line 74
if 'collate_fn' not in config['loader'] or config['loader']['collate_fn'] is None or len(config['loader']['collate_fn']) == 0:
#config['loader']['collate_fn'] = None # here has to changle,========= 这里要改成下面的，不然传None进去会被直接赋值 ====
config['loader']['collate_fn'] = torch.utils.data.dataloader.default_collate
else:
config['loader']['collate_fn'] = eval(config['loader']['collate_fn'])()
_dataset = get_dataset(data_path=data_path, module_name=dataset_name, transform=img_transfroms, dataset_args=dataset_args)
sampler = None
if distributed:
from torch.utils.data.distributed import DistributedSampler
# 3）使用DistributedSampler
sampler = DistributedSampler(_dataset)
config['loader']['shuffle'] = False
config['loader']['pin_memory'] = True
loader = DataLoader(dataset=_dataset, sampler=sampler, **config['loader'])
return @loader
如此，再训练，就ok了！！！
赶紧训练，并用自己的数据训练看看！
