{Critical} Value Error: node array from pickle has incompatible dtype

[theharshith]

Hello, Thanks for this wonderful repo!

When i git clone and run this using python etoxpred_predict.py --datafile tcm600_nr.smi --modelfile etoxpred_best_model.joblib --outputfile results.csv (after unzippiing tar) i get this error:

I tired reducing sk-learn to base version -> didnt work installed MS visual tools and C++ tools -> didnt work

Kindly help me through this. Much Appreciated

Is your sk-learn version 2.3?

[theharshith]

Nope, mine is on version 1.4 when I try to run pip install --upgrade scikit-learn==0.24 I get this error:  

note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for scikit-learn
Failed to build scikit-learn
ERROR: Could not build wheels for scikit-learn, which is required to install pyproject.toml-based projects

Issue with the package error.

I'm getting the same error when I attempt to change the scikit-learn version back to 0.24 as well

I did not have that problem on my system. I'm using RHEL 8. What is your system spec? And do you do it under venv with Anaconda?
