Missing 'PRISM_interval_vector.csv' after Syntax error

[Miracle-qi]

When I run the RunFile.py and all the examples in run_experiments.sh，the following error happened without generating PRISM_interval_vector.csv as expected. I would greatly appreciate it if you could provide some guidance or information to help resolve this issue.

Error: Syntax error ("?", line 1, column 9).

My apologies for never replying to your issue. I had my notifications set wrongly, so I never got notified of your issue; sorry for that!

The line rewards_k0 = pd.read_csv(vector_file, header=None).iloc[self.mdp.head:].to_numpy() should read the results from PRISM back into Python. While I have not encountered this error myself before, I suspect that either this PRISM output file is corrupted, or something is wrong within Pandas.

If the error still persists, could you paste the content of PRISM_interval_vector.csv (located in the relevant output folder), and in addition let me know what Python package versions you used (e.g., using a pip list)?

That said, the code and the dependencies have changed quite a bit since, so it could also be that the issue has already been mitigated.
