We have pushed a new version of the obstacle-tower-env package (v1.2). Here are the changes:

  • Adds timeout_wait parameter to extend python wait time for Unity environment handshake.
  • Adds realtime_mode parameter to launch Unity environment from API at real-time speed and render to the window.
  • Updates Windows and Linux binaries to address launching issues.

If you have experienced issues launching the environment from our api on Windows or Linux, please download the new binaries, upgrade the python package to v1.2, and try again.
