Not able to render on Colab

[Vibha111094]

The below command:

python -m alfred.gen.render_trajs

works when i run it on my personal laptop, but does not seem to work on colab.

Are there any changes I can do so that I can get it working on colab.

Hi Vibha,

To render the trajectories, you need to have an X server running. By default, the code uses 0 for the X server display number and you can change it with args.x_display. We never tried to run the code with colab but you can try to do it by making sure that an X server is running at your backend device. It should be easier if you chose your local machine as a backend and check that an X server running (e.g. with xdpyinfo).

Best,
Alex
