add os.environ['CUDA_VISIBLE_DEVICES'] = 0 in experiments.py

Hello and congrats for this amazing project. I modified the following code, because I had issues in the training process. Now it works like a charm.

Hi, thanks for reporting your changes and submitting the PR!

Hard-coding 'CUDA_VISIBLE_DEVICES' to 0 would disable the possibility to run multi GPU training, so I cannot accept it.

Regarding the other changes, their are specific to your system and ROS users, so I'd rather keep the current code as generic as possible and not include it. Otherwise we would have to handle cases for anaconda users, for ROS ones, etc.

So I'll close this PR for now, but you could instead fill an issue with your experience, so that other users of ROS or who are having trouble with the GPU can do the changes themselves locally.

Τhank you for the quick response.

It's absolutely understandable to not accept the PL. I'll open an issue with my changes in the code as soon as possible.
