Hey! I’m having the same problems even after following the instructions.
I have a ‘tensorboard.exe’ in my ‘C:\Program Files\Epic Games\UE_5.3\Engine\Binaries\ThirdParty\Python3\Win64\Scripts’ directory.
And still get this error;
LogLearning: Display: Training Process: Warning: Failed to Load TensorBoard: No module named ‘tensorboard’. Please add manually to site-packages.
Did you solve this issue?
