I followed this tutorial
and no matter what I did the “Make PPOTrainer” node always returns None.
I tried directly linking the “Make Critic” etc nodes’ outputs to the “Make PPOTrainer” node and putting 0.2sec delays between the “Make …” nodes but that did not change anything.
Hello, I encountered the same problem. Did you find a way to solve it?
When I examined my log file, I encountered an error saying that the “python.exe” file could not be found in the specified location. I noticed that the path it mentioned was in the “Trainer Process Settings” of the “Spawn Shared Memory Training Process” function in the Manager file. When I replaced the path in the default value section of this variable with my own Intermediate path, this problem was solved.
