    I used ML Agents (Version 1.7.0 preview) in Unity to train my agent last year and saved model. But when I update ML Agents to Version 2.1.0 exp now and load the same model trained in earlier version, the agent shows totally different movement in the same env.

    Any ideas? Thanks a lot.

    downgrade to <2? Retrain from scratch? Technically, if one is using semver, https://semver.org/ , then major version upgrades == backwards incompatible / breaking changes. Going from 1.x.x to 2.x.x is a major version upgrade, and therefore could indicate a backwards incompatible / breaking change.
