在python ctypes中安装Pytork时出现问题。CDLL（dll）OSError:[WinError 126]找不到指定的模块

Question

我正在尝试从https://github.com/CSAILVision/places365运行run_placesCNN_basic.py代码。 我正在运行Windows10和Python 3.7.9

我打开命令提示符并尝试安装pytorch：

py -m pip install torch==1.6.0+cpu torchvision==0.7.0+cpu -f https://download.pytorch.org/whl/torch_stable.html

我得到以下过程：

C:\Users\..\Downloads\places365-master>py -m pip install torch==1.6.0+cpu torchvision==0.7.0+cpu -f https://download.pytorch.org/whl/torch_stable.html

最后，我尝试运行.py文件：

C:\Users\..\Downloads\places365-master>py run_placesCNN_basic.py
Traceback (most recent call last):
  File "run_placesCNN_basic.py", line 6, in <module>

    self._handle = _dlopen(self._name, mode)
OSError: [WinError 126] The specified module could not be found

有人知道为什么我不能运行pytorch模块，即使我已经安装了它吗
