不完整的 PyTorch 与任何 CUDA 版本（模块“火炬”没有属性“cuda”）

Question

I have NVidia 1080TI, Ubuntu x64, and Python 3.6.9 installed. I was trying to launch PyTorch with command

import torch
print(torch.cuda.is_available)

and expected to see 'True' but met the error:

AttributeError: module 'torch' has no attribute 'cuda'

I tried to update PyTorch and install the last version 1.7.0 with CUDA 11.0 support. After that, I noticed some version discrepancies. nvidia-smi shows CUDA version 11.0 but nvcc -V shows 9.1. Also, I used cat /usr/local/cuda/version.txt to check CUDA version but got the error: cat: /usr/local/cuda/version.txt: No such file or directory I installed CUDA driver 450.33 after fully nvidia purging but the error remains and nvcc -V still shows 9.1 version (after reboot also).
One more option I addressed to is conda installation but it didn't help. What I can do to resolve the problem?

Answer 1

As a result, I had a file named torch.py in my home directory. After the renaming problem was solved.
Thanks. Maybe my answer will be helpful to someone.

Answer 2

I had the same problem and reinstalled it several times, only to find that my script was named torch.py
