Description
Hi
There was a problem while training.
When I write the code, I get the following error. How do I fix it?
!python3 main.py --base-dir IA2C train --config-dir config/config_ia2c_large.ini --test-mode no_test
error :
Loading configuration ... done.
Error: File './large_grid/data/exp.net.xml' is not accessible (No such file or directory).
Quitting (on error).
