Environment info

LightGBM version or commit hash:

I used PyCharm's library installation and then I tried installing with the pip command. Also, I tried to install 3.3.2 version instead of the latest version

Thanks for using LightGBM.

LightGBM expects by default to find OpenMP installed locally, and to be able to dynamically link to it. It appears from this line that you don't have it installed.

ninja: error: '/opt/homebrew/opt/libomp/lib/libomp.dylib', needed by '/private/var/folders/y4/jnpd1pl92r50hk6sfmrcq20c0000gn/T/pip-install-nj8eih_s/lightgbm_fbb81935721e47e2b01bf4ab5b7285c7/lib_lightgbm.so', missing and no known rule to make it

Since it appears from the logs you provided that you're on a Mac, you can install it like this:

brew install libomp

Alternatively, if you don't want to use OpenMP, you can install a version of lightgbm that does not use OpenMP. Training and prediction will be slower (as a result of not using multithreading), but you'll be able to build lightgbm.

If you absolutely have to stay on lightgbm v3.3.2, run the following

pip install 'pip<23.1'
pip install \
    --no-binary lightgbm \
    --install-option='--nomp' \
    'lightgbm==3.3.2'

The pip ceiling is because pip v23.1 removed support for --install-option: #5061 (comment).

If you can upgrade to lightgbm v4.0.0, please do. It contains almost 2 years of performance enhancements, bugfixes, and new features relative to v3.3.2. With that version, you can install a no-OpenMP version like this:

pip install --upgrade pip
pip install \
   --no-binary lightgbm \
   --config-settings=cmake.define.USE_OPENMP=OFF \
   'lightgbm>=4.0.0'

Many of these details, and others about installation of the Python package, are available at https://github.com/microsoft/LightGBM/blob/master/python-package/README.rst.

Also note... I've edited your post to make the difference between text you wrote, commands you ran, and logs from those commands clearer.

Please see https://docs.github.com/en/get-started/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax for information on how to format text on GitHub.

Thanks, I finally installed LightGBM, also I'll look at the guide before I write a problem.
