pytorch1.60 torch.nn在pycharm中无法自动智能提示的解决
作者:雪的期许
问题描述
安装了pytorch最新版本1.6之后,在pycharm中编辑python代码时,输入torch.nn.
看不到提示了,比如torch.nn.MSELoss()
。
而在1.4及以前的版本中,直接输入torch.nn.
就会自动提示出很多torch.nn.modules中的API。
该问题的讨论在前几年有过不少,但都是基于老版本,经过尝试,对于1.6版本是无效的。
原因分析
pycharm的自动提示是根据第三方包的每个文件夹下的__init__.pyi
文件来显示的,只有__init__.pyi
中import了的API才会被pycharm自动提示。
首先对pytorch.nn
模块要知道,问题描述中提到的MSELoss
等众多函数,真实位置是torch.nn.modules.MSELoss()
,你直接调用这个真实位置是可以自动提示的。
但是1.4及以前的版本中大家都熟悉了直接用nn.MSELoss()
这样调用,如何让1.6版本也能像历史版本一样提示呢?
基于此,我对比了1.6和1.4的区别。
在torch 1.6版本包存放位置下,torch/nn/
下是有__init__.pyi
的,里面有一行from .modules import *
,说明nn
模块是可以直接调用子模块modules
中的API的,所以直接调用nn.MSELoss()
不会报错,只是不会自动提示。
然后在进入torch/nn/modules/
发现,1.6版本中缺少__init__.pyi
文件,所以在pycharm输入nn.
的时候并不会提示子模块modules
中的API。
解决方案
从pytorch 1.4版本中复制一份__init__.pyi
文件到1.6版本的依赖包的相同目录下。
具体位置是:
{你的第三方包存放位置}/Lib/site-packages/torch/nn/modules/__init__.pyi
然后就可以在pycharm中愉快使用nn.
自动提示了。其他模块不自动提示的,解决方法类同。
补充
关于解决方案中第三方包存放位置不知道的,可以在pycharm左侧项目目录结构中看到一项External Libraries
,点开它,你就能直接找到Lib/site-packages/torch/nn/modules/
,从而不必去资源管理器找。
