2020+ Exception: 'DataFrame' object has no attribute 'ix'

Question

[chenglei1865]

When I used 2020+ to analyze example date, one error occurred at step 55

python `which 2020plus.py` --out-dir output_bladder/pretrained_output --log-level=INFO classify -n 200 --trained-classifier data/2020plus_10k.Rdata -d .7 -o 1.0 --features output_bladder/features.txt --null-distribution output_bladder/simulated_null_dist.txt --random-seed 71 --cv

Check for pandas library usage within python code. Probably, it's written for earlier versions of pandas.

Thank you for your reponse! I uninstalled current pandas(1.5), and I tried installed 0.17,0.18, errors occurred: Running setup.py clean for pandas Failed to build pandas Installing collected packages: pandas Running setup.py install for pandas ... error ERROR: Command errored out with exit status 1: command: /home/ug0416/.conda/envs/2020plus/bin/python -u -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'/tmp/pip-install-fkpkj06m/pandas_db40b85687e043a995bafbc57b16500a/setup.py'"'"'; __file__='"'"'/tmp/pip-install-fkpkj06m/pandas_db40b85687e043a995bafbc57b16500a/setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);

current version is 1.3.4 as per https://pandas.pydata.org/. Please check your pandas versions.
