First of all, I would like to highlight that there were many problem with CMakeLists.txt file. It took me around 3 days to fix them. Here is the corrected CMakeLists.txt for future reference for someone else to use. I deployed it on Linux 20.04 with ROS Neotic.
CMakeLists.txt
I would like to mention that I used develop branch as it used gymnasium. However, upon running
python3 policy_compression_train.py
I got following error.

.../casadi/core/function_internal.hpp:1649: Input 0 (samples) has mismatching shape. Got 3-by-20. Allowed dimensions, in general, are:
- The input dimension N-by-M (here 2-by-20)
- A scalar, i.e. 1-by-1
- M-by-N if N=1 or M=1 (i.e. a transposed vector)
- N-by-M1 if K*M1=M for some K (argument repeated horizontally)
- N-by-P*M, indicating evaluation with multiple arguments (P must be a multiple of 1 for consistency with previous inputs)
Can you confirm that your develop branch code works for RL please? Thank you so much for your time and efforts.
