Hello I’m new to Pytorch and I’ve been trying to work through this tutorial.
[https://github.com/pytorch/tutorials/blob/master/intermediate_source/torchvision_tutorial.rst 15]
I’m using Visual Studio Code, conda installed the Pytorch. Initially the issue was that it was missing the module engine. But this problem was solved here:

  
    
    
    ModuleNotFoundError: No module named 'engine' 
  
  
    So how do we get the references/detection/ folders? What should we download and install? I have installed the pytorch, torchvision in my environment, but I could not find those files. Thanks
  


With a step I misread.
So I downloaded and copied the pycocotools into the project directory and the vision/detection/ .py files in to it too.
That being done it fixed that issue but the error it is now giving is.
(base) C:\Users\Sean\Desktop\Project\Test\Tutorial>D:/Anaconda/python.exe c:/Users/Sean/Desktop/Project/Test/Tutorial/tv-training-code.py
Traceback (most recent call last):

  File "c:\Users\Sean\Desktop\Project\Test\Tutorial\pycocotools\mask.py", line 3, in <module>
    import pycocotools._mask as _mask
ModuleNotFoundError: No module named 'pycocotools._mask'

I’m not quite sure what the issue here is or how to fix it. Given that the _mask.pyx is present and is what I think is being imported. As I said I’m not to sure what the issue is but I would appreciate the help.
