Reports

I have try all methods, but my question is not reslove, and my question is

>>> import torch
>>> print(f'CUDA Available: {torch.cuda.is_available()}
  File "<stdin>", line 1
    print(f'CUDA Available: {torch.cuda.is_available()}
                                                      ^
SyntaxError: EOL while scanning string literal
>>> print(f"CUDA Device Name: {torch.cuda.get_device_name(0)}")
Traceback (most recent call last):

    torch._C._cuda_init()
RuntimeError: CUDA unknown error - this may be due to an incorrectly set up environment, e.g. changing env variable CUDA_VISIBLE_DEVICES after program start. Setting the available devices to be zero.

I try sudo apt-get install nvidia-modprobe, sudo reboot .I use lxc container, the cuda is 11.7. torch is 1.13.0+cu117, nvidia is 535, please help me . thank you
