import issue with pycaret library in juypter notebook in anaconda environment in mac OS

Encountered issue shown in the following section during pycaret library import in locally installed jupyter notebook in Anaconda Navigator 2.5.1 in Mac OS 10.13.6, python 3.8 environment. Error stack was received while importing from pycaret.classification import * and same error will also be encountered with other classes (i.e. from pycaret.classification import * and from pycaret.regression import validate_params) though the installation of pycaret was successful.

Suspecting pycaret library issue, attempt !pip install pycaret --upgrade, !pip uninstall pycaret, and !pip install pycaret but no lock in resolving the issue. Also, tried downgrading to pycaret 2.3.3, as in pycaret version 2.3.3, the prefer_skip_nested_validation argument was made optional. Unfortunately, downgrade couldn't successed due to many dependency failures, it may be because of the version released 27 months back and has had many updates in the dependent packages. Any suggestion resolving the import issue would be appreciated.

Solution

  • I faced the same issue and referred to a post, and I was trying this in Jupyter Notebook in Conda environment. !pip install --pre pycaret It successfully install package but while I am importing package it was giving error : enter image description here

    ModuleNotFoundError: No module named 'pycaret'

    The same package it successfully installed and run fine in Google colab as below.

    enter image description here

    It clearly indicates that the environment where we are installing and trying to run in Pycarate having some issues. I could not find any way to fix that.

    But I found some workaround like below. Please execute command I hope it will help.

    1. conda info --envs. It will list the available env in your python.
    2. conda activate <Select_one_Env> Select_one_Env is the potential sample env name that is going to be selected. You select the best env for your use case.

    I believe you are already doing the above 2 steps. The following steps will bypass the Jupyter Notebook and try to work with ipython .

    ipython Is similar to Jupyter Notebook but is in a shell or console terminal.

    Once the target env is selected use the following command.

    enter image description here

    Now you will be able to run pycrate package in ipython shell.

    Hope, It will help to solve the issue.
