System can not find the route

[haolema]

Hello, I want to ask you a question. When I used the texst.py file for testing, the following error occurred
[WinError 3] The system cannot find the path specified. :'d\_valid_cache'
which is occurred in "win_det_heatmaps-master\common_pytorch\dataset\imdb.py", line 32, in cache_path
os.mkdir(cache_path)"
I would like to ask you how to solve this problem?
Thank you so much!
