Error reproduce experiments

[Yunshan Jia]

Hello,

I am not sure if I should reproduce experiments by this command, I just want to run some tests in ghost paper, so I tried this:

Could you please tell me how to fix it?

same error occurs for other tests in scripts dir

Hi,

Does this also happen when you run the par files directly from the project root? Here is an example:

./bazel-bin/experiments/scripts/centralized_queuing.par cfs

Closing this. Feel free to reopen if you are still having this issue.

Thank you very much for your help, I found another way to solve it.
