Failed to generate coverage report

[Federico Cernera]

When running the command ./run_all_experiments.py -y ./benchmark-sets/comparison/tinyxml2.yaml --model='gpt-3.5-turbo, I encounter the following error:

The issue is related to the port number. The value 0 is not a valid port number.

Thanks for reporting the issue, @fedecerno!
Could you please check if #113 fixes this on your machine?

It changes 0 to an empty string, which should have the same effect but avoids using 0 directly.

[Federico Cernera]

Yes, I confirm that #113 fixes this problem.

[Dongge Liu]

Yes, I confirm that #113 fixes this problem.

Thanks!
