    Hi, i have the following settings
    upload_2021-6-29_20-24-29.png

    and i noticed i have "Freeze" from time to time (every X time the game freezes for 1-2 seconds), i have a InvokeRepeating(nameof(CustomUpdate), 0f, 0.1f);

    where the customUpdate method is requesting a decision.
    this is the config file i have:

    Hi,
    is the "freeze" happening during training? If so, this is expected as the python process needs to update the weights of the neural network in order to improve the model you are training.

    Hi,
    I'm reaching out to our research team to see if significant changes to the trainers went in release 17 that may have caused this.

    Hi @mamaorha,
    In release 17 the threading property is set to false by default. This means that the environment does not step while the python update is happening. Previously it threading was set to true by default. This should not have an effect on overall training times.
