Pytorch问题：ModuleNotFoundError: No module named ‘torchnet‘ ， ‘pip._internal‘已解决

bug1: ModuleNotFoundError: No module named 'pip._internal'

出错提示： 

File "D:\app\anaconda\envs\pytorch_gpu\Scripts\pip.exe\__main__.py", line 4, in 
ModuleNotFoundError: No module named 'pip._internal'

解决：
       找到提示的路径（D:\app\anaconda\envs\pytorch_gpu\Scripts\）下的pip.exe，删了。

       然后用下边两句强制重新安装：

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python3 get-pip.py --force-reinstall

       然后会报下边这个警告，升级一下pip：

You should consider upgrading via the 'd:\app\anaconda\python.exe -m pip install --upgrade pip' command.

解决：

pip install --upgrade pip -i http://pypi.douban.com/simple/ --trusted-host=pypi.douban.com/simple

安装成功~

No module named 'pip._internal'问题已解决~~~

bug2: ModuleNotFoundError: No module named 'torchnet'

程序报错：

from  torchnet import meter

ModuleNotFoundError: No module named 'torchnet'  

解决：

搜了网上的教程，提示

>pip install git+https://github.com/pytorch/tnt.git@master -i http://pypi.douban.com/simple/ --trusted-host=pypi.do
uban.com/simple
pip install --upgrade git+https://github.com/pytorch/tnt.git@master
 

报错：

1、直接用pip install torchnet

报错：

Requirement already satisfied: torchnet in d:\app\anaconda\lib\site-packages (0.0.5.1)
Requirement already satisfied: future in d:\app\anaconda\lib\site-packages (from torchnet) (0.18.2)
Requirement already satisfied: torch in d:\app\anaconda\lib\site-packages (from torchnet) (1.8.1)
already satisfied: certifi>=2017.4.17 in d:\app\anaconda\lib\site-packages (from requests->visdom->torchnet)

解决：首先得Make sure you have PyTorch installed, then do: 

pip uninstall torchnet

需要指定到pytorch所在的文件路径下

pip install --target=D:\app\anaconda\envs\pytorch_gpu\Lib\site-
packages  -i https://pypi.doubanio.com/simple/  --trusted-host pypi.doubanio.com  torchnet
