So I’ve been modifying the Hot Gym swarm.py file and swarm_description.py to take my own data with success. It has been working fine with 2 float columns and 1 datetime column as inputs. When I changed the input to 5 floats and 1 datetime column it works initially, but a few seconds later an error appears:
TypeError: Parameters columnCount and inputWidth must be > 0
This wasn’t an issue before so I’m a bit stumped. Any ideas?
Thanks 
You are dabbling in very legacy code. My guess is that swarming changed columnCount or inputWidth to an invalid value.
Does the swarming data file have 5 float fields and 1 datetime column?
Yes that is correct
It’s interesting that the swarm would do this; surely it has constraints for this sort of thing? Maybe it’s worth looking into the permutations file seeing as I have let it be and focused on the description file so far.
Just ran a few tests and it seems to be ok, when a particular column is removed not sure why.
Maybe there is some bad data in this column? Nulls or wrong types?
