AssertionError

This AssertionError comes when I use seed mechanism in input.py file. Can someone please help me?

I am completely stuck at this point. Can someone please help me to move forward.

It looks like you are failing one of the assert statement checks in this function but I can't tell which one since the line numbers don't match up. You might be running an outdated version of RMG-Py, so I recommend upgrading.

Those functions should also give more descriptive output about why they failed - check your terminal and logfiles to see if there is anything else.
