Test after adding environment variables , You can see conda edition 4.5.11

3、Anaconda Install in virtual environment CUDA

How to view cuda Version of ？ see CUDA edition

I installed CUDA 11.3.0 Automatically install the corresponding version cudnn 8.2.1​

 4、 use anaconda install pytorch

Code debugging encountered problems ：No module named ‘torch‘

You need to install pytorch, Then import torch package

​

PyTorch Official website ：PyTorch

Big guy's installation tutorial , fantastic ！！！ Give it to the boss for three times + A chicken leg

The video introduces anaconda Next, create a virtual environment , How to install step by step pytorch, Last in pycharm How to add virtual environment in the project .

Be careful ！！！ The pit appeared ！！！, In the installation order given on the official website ,-C The parameter indicates Pytorch Download source of installation , When executing this command here , Must put -C Parameters are followed by pytorch Get rid of , Otherwise, tortoise speed will come again ！

5、CUDA driver initialization failed

Install well pytorch The latter question ：CUDA driver initialization failed, you might not have a CUDA gpu.​

This is because CUDA You need a suitable version of the graphics card driver .

my CUDA=11.3, Then my graphics card driver version will >=452.39​

View the graphics card driver version scheme 1 ： stay cmd Next use nvidia-smi command , Pictured ​

Windows NVIDIA Corporation Under no NVSMI Folder solution ：

  View the graphics card driver version scheme II ： Open it directly NVIDIA Control panel view ​

Check that my graphics card driver version is too low , At this time, you need to upgrade the driver

Successfully upgraded the driver to 457.51 edition , As shown in the figure below
​

Then install CUDA Virtual environment verification CUDA Whether it can be used normally

print(torch.cuda.is_available) 

​

Output True

Be accomplished ！
