File not found error

i am having the following issue FileNotFoundError: Could not find module ‘C:\Users\ritik\Anaconda3\envs\fastai_v1\lib\site-packages\torch\lib\caffe2_nvrtc.dll’ (or one of its dependencies). Try using the full path with constructor syntax.
note- i don’t have a gpu and i have followed line by line instructions of the installation process, so kindly help me with this.
