1. pip install --special_version
pip10.0.1 以上的版本安装包报一堆错误，所以降级为9.0.3 版本。
使用命令：
python -m pip install pip==9.0.3
其中， -m 参数的意思是将库中的python模块用作脚本去运行[1]
run library module as a script (terminates option list)
2. fusibile make error
在编译 fusibile 时出现错误
最开始是 cmake .. 都没有通过，因为没找到 OpenCV 链接库，在装好 OpenCV 之后问题解决，顺利通过
然后 make 又出错，错误提示如下
1 ~/mvsnet/fusibile/build$ make 2 [ 33%] Building NVCC (Device) object CMakeFiles/fusibile.dir/fusibile_generated_fusibile.cu.o 3 ptxas info : 77824 bytes gmem, 72 bytes cmem[3] 4 ptxas info : Compiling entry function '_Z8fusibileR11GlobalStatei' for 'sm_30' 5 ptxas info : Function properties for _Z8fusibileR11GlobalStatei 6 8192 bytes stack frame, 0 bytes spill stores, 0 bytes spill loads 7 ptxas info : Used 47 registers, 332 bytes cmem[0], 20 bytes cmem[2] 8 ptxas info : 77824 bytes gmem, 72 bytes cmem[3] 9 ptxas info : Compiling entry function '_Z8fusibileR11GlobalStatei' for 'sm_52' 10 ptxas info : Function properties for _Z8fusibileR11GlobalStatei 11 8192 bytes stack frame, 0 bytes spill stores, 0 bytes spill loads 12 ptxas info : Used 48 registers, 332 bytes cmem[0], 20 bytes cmem[2] 13 /usr/include/string.h: In function ‘void* __mempcpy_inline(void*, const void*, size_t)’: 14 /usr/include/string.h:652:42: error: ‘memcpy’ was not declared in this scope 15 return (char *) memcpy (__dest, __src, __n) + __n; 16 ^ 17 CMake Error at fusibile_generated_fusibile.cu.o.cmake:266 (message): 18 Error generating file 19 /home/cvlab/mvsnet/fusibile/build/CMakeFiles/fusibile.dir//./fusibile_generated_fusibile.cu.o 20 21 22 CMakeFiles/fusibile.dir/build.make:63: recipe for target 'CMakeFiles/fusibile.dir/fusibile_generated_fusibile.cu.o' failed 23 make[2]: *** [CMakeFiles/fusibile.dir/fusibile_generated_fusibile.cu.o] Error 1 24 CMakeFiles/Makefile2:67: recipe for target 'CMakeFiles/fusibile.dir/all' failed 25 make[1]: *** [CMakeFiles/fusibile.dir/all] Error 2 26 Makefile:83: recipe for target 'all' failed 27 make: *** [all] Error 2
参考网友【@cheney康】编译opencv2.4.13error 的解决方案，对 g++ 版本进行兼容设置，在 CMakeLists.txt 中添加
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -D_FORCE_INLINES")
再运行make出现下面的信息，应该算是已经通过了？

3. 硬盘挂载问题
问题描述：电脑权限紊乱导致的当前用户无法读取外接硬盘的内容。
硬盘信息展示， Name 是 Linux filesystem，所以我的硬盘是什么格式的呢？
1 cv@cv:~$ sudo gdisk /dev/sdb 2 GPT fdisk (gdisk) version 1.0.1 3 4 Partition table scan: 5 MBR: MBR only 6 BSD: not present 7 APM: not present 8 GPT: not present 9 10 *************************************************************** 11 Found invalid GPT and valid MBR; converting MBR to GPT format 12 in memory.

让我产生这种疑问的是下面的信息：
1 cv@cv:~$ sudo fdisk -l 2 Disk /dev/sdb: 465.8 GiB, 500107862016 bytes, 976773168 sectors 3 Units: sectors of 1 * 512 = 512 bytes 4 Sector size (logical/physical): 512 bytes / 4096 bytes 5 I/O size (minimum/optimal): 4096 bytes / 33553920 bytes 6 Disklabel type: dos 7 Disk identifier: 0x49e2c54e 8 9 Device Boot Start End Sectors Size Id Type 10 /dev/sdb1 * 2048 976769023 976766976 465.8G 83 Linux

硬盘内容明明是存在的，却无法读取到，非常奇怪。
