Using PyCaret for the first time. Installed Anacoda using command line and then install PyCaret inside the Jupyter Notebook.

PyCaret installed is successful because this following code works:

from pycaret.datasets import get_data
jewellery = get_data('jewellery')

But when using following code:

from pycaret.clustering import *

The following error comes:

-

Any help would be greatly appreciated?

If your os is Mac.

brew install libomp

solves the problem.

  • Yes. I also saw this solution here: https://pycaret.org/install2/ Could you please explain where do I run this command? In the terminal OR Jupyter notebook? – Sparsh Chugh Dec 20 '21 at 15:42
  • Ofcoure in terminal. check this out https://brew.sh/ – paul kim Dec 20 '21 at 22:59
  • Done all the steps. Issue still remains the same – Sparsh Chugh Dec 21 '21 at 13:01
  • Do you use virtualenv for pycaret? – paul kim Dec 21 '21 at 13:49
  • Let me check. I met same issue like u. First is i didn't brew install libomp. Second is i didn't use virtual env. You seems like using anaconda3 with out virtualenv. check this out ! you need use virtualenv for your PyCaret because PyCaret have many dependencies . https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html After you setup virtualenv, install PyCaret at first. – paul kim Dec 21 '21 at 13:54
  • ✅ Virtual Environment ✅ CMake ✅ OpenMP ✅ libomp ✅ lightgbm ❌ Classification: from pycaret.classification import * ❌ Regression: from pycaret.regression import * ❌ Clustering: from pycaret.clustering import * ❌ Anomaly Detection: from pycaret.anomaly import * ✅ Natural Language Processing: from pycaret.nlp import * ✅ Association Rule Mining: from pycaret.arules import * – Sparsh Chugh Dec 21 '21 at 14:21
