running retropath2 on colab?

[bbanzai88]

Hi, I am trying to run Retropath2 on colab.

I have tried this (with both capital R and capital P and lower case r and p) and with and without the kexec):
from retropath2_wrapper import retropath2
import knime
kexec='/usr/local/lib/python3.10/dist-packages/knime/bin/knime'

Create an instance of the RetroPath2 class

r_code = retropath2(
sink_file='/content/sample_data/sink.csv',
source_file='/content/sample_data/source.csv',
rules_file='/content/sample_data/rules.csv',
outdir='/content/sample_data/out',
max_steps=3,
topx=100,
dmin=0,
dmax=100,
mwmax_source=1000,
kexec='/usr/local/lib/python3.10/dist-packages/knime/bin/knime'
)

and got this: ---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
in <cell line: 6>()
4
5 # Create an instance of the RetroPath2 class
----> 6 r_code = retropath2(
7 sink_file='/content/sample_data/sink.csv',
8 source_file='/content/sample_data/source.csv',

TypeError: 'module' object is not callable_

Any ideas on what I can do would be greatly appreciated!! Thank you!!
