No Images in tensorboard #1

Open hanshublyh opened 3 months ago

Thanks a lot for your sharing about CS285 HW.

Hi, I am now learning the CS285, a problem in hw1 that has troubled me for a few days is that there is no Image or video in tensorboard. There are only scalars. So I want to seek your help.

My experiment OS is WSL Ubuntu 20.04.

Here is the training output:

It seems that there is no error? Only Can't import moviepy.editor. But the packages imageio and requests are in my conda env.

I don' know why I cannot see the videos, the hw1 may not be very difficult but some problems like this really annoy me a lot. Thanks a lot for you attention and help.

I wonder if you have met such a problem before or if you have any idea about that. Thanks a lot for your help!

Hi, sorry for late reply. I haven't been involved in reinforcement learning research for quite some time.

Based on the error message alone, I suspect it might be because you installed the latest version of moviepy, and moviepy.editor might have been moved to a different location in the latest version.

Thanks for your reply!

I changed the moviepy into a lower version, but sadly there is still no video in the tensorboard. And it seems that there is also no good solution for the problem on the Internet. Today I ran the experiment on Colab, and the configuration for 20Fall's hw has some errors, but the 23Fall hw's output is right. So I decide to finish all the hw on Colab. Homework frst and coding environment second hhh.

All in all, thanks again.
