Training is ok, but failed to eval.

Hello👋,

Thank you for open-sourcing the code for the min decision transformer. Your code has been tremendously helpful in helping me understand DT.

However, I am currently facing an issue. During the training process, the action loss is indeed steadily decreasing, but the test results have consistently been subpar, to the point of having no discernible impact. I've been grappling with this problem for a while now and can't seem to figure out why this is happening.

By the way, I haven't tested it on the three environments, namely halfcheetah, hopper, and walker2d, mainly because I've been struggling with configuring d4rl. I'm using the upgraded version of d4rl provided by Farama, specifically on the pointmaze offline dataset.

If you could spare some time to assist me with this, I would be immensely grateful!

The Decision Transformer paper does not provide results for pointmaze environment, it is a difficult env and I would not expect DT to work well on it out of the box.

If you are struggling to install d4rl, you can refer to the first couple of blocks on the colab notebook in the repo that installs the required libraries on google colab.

May DT failed to do path planning. I have tried it on the Minari dataset. It seems like it can only work in the Umaze environment.
