TPOT report error
Today when I ran a machine learning project using TPOT, it reported the error below:
D:\rebirth - default\venv_test\Lib\site-packages\tpot\builtins\__init__.py:36: UserWarning: Warning: optional dependency `torch` is not available.
- skipping import of NN models.

The code was successfully ran three months ago. But I updated the python libraries last week. I guess some updated libraries resulted in this error.
Assigned to Nick to keep visibility on the issue. Nick to take a look and decide if it needs to be assigned to someone else in the team.
I can confirm this. When I tried to run on my local machine using a fresh conda environment on Python 3.10.13, the code gave me the above error. However, when I ran it on a Kaggle environment, it worked.
After checking around, I tried reinstalling dependencies on my local environment with the versions on the kaggle environment and it worked locally.
These are the versions that worked for me:
pandas==2.2.0 numpy==1.24.4 matplotlib==3.7.4 seaborn==0.12.2 scikit-learn==1.2.2 scipy==1.11.4 TPOT==0.12.1 gplearn==0.4.2 torch==2.1.2 termcolor==2.4.0 sympy==1.12
Has the latest update resolved your issue? Should be working with the latest version of scikit-learn now
