我无法加载我的模型，因为我无法放置 PosixPath [英] I can't load my model because I can't put a PosixPath

问题描述

我正在设置一个脚本，我需要使用 fast-ai 包中的一些函数.事实是，我在 Windows 上，当我定义路径时，fast-ai 中名为 load_learner 的函数无法加载模型.

I'm setting up a script and I need to use some functions from fast-ai package. The fact is that I'm on Windows and when I define my paths, the function from fast-ai named load_learner can't load the model.

我尝试将函数更改为包:

I've tried to change the function into the package as:

state = pickle.load(open(str(path) + '/' + str(fname), 'rb'))

代替:

state = pickle.load(open(path/fname, 'rb'))

但我收到此错误:

 File "lib\site-packages\fastai\basic_train.py", line 462, in load_learner
    state = pickle.load(open(path/fname, 'rb'))
  File "\lib\pathlib.py", line 1006, in __new__
    % (cls.__name__,))
NotImplementedError: cannot instantiate 'PosixPath' on your system

我的路径定义为:

folder_path = './models/model1'
fname = 'model.pkl'

我把这个函数称为:model = load_learner(folder_path, fname)

如何在此功能中使用 Windows 路径?

How can I use Windows paths in this function?

发布的答案仅在 Linux 上是正确的.我在 Windows 上仍然有这个问题.我没有找到在 Windows 上通过 PosixPath 的方法.我发现的唯一解决方案是从我的模块中更改内部包，但这不是解决此类问题的安全方法.

The answer posted was correct only on Linux. I still have the issue on Windows. I didn't find a way to pass through the PosixPath on Windows. The only solution that I found is to change the internal packages from my modules but it is not a secure way to solve this kind of issue.

提前致谢.

推荐答案

根据我自己的问题，我找到了一个方法:

According my own question, I find a way using:

from pathlib import Path

folder_path = Path('./models/model1')

此解决方案仅适用于 Linux，在 Windows 上我仍然遇到错误.

UPDATE 1

This solution only works on Linux, on Windows I still get an error.
