Missing DONKEY_SIM_PATH environment var

Hi,

I am trying to run the train.py file with the followig command: python train.py --algo sac -vae pretrained_vae/vae-level-0-dim-32.pkl -n 5000

I get the following logs:

Starting DonkeyGym env
Missing DONKEY_SIM_PATH environment var. We assume the unity env is already started
Binding to ('0.0.0.0', 9091)
Waiting for sim to start...if the simulation is running, press EXIT to go back to the menu

It keeps printing the last line over and over.

So, I tried to create an environment variable called DONKEY_SIMPATH pointing with the following path \learning-to-drive-in-5-minutes\donkeygym

I get the following error while running the script:

The script is run on Windows. Would have any idea how to solve this issue?

Many thanks for your help
