Testing your installation

To make sure MNE-Python was installed correctly, type the following command in a terminal:

python -c "import mne; mne.sys_info()"

Hint

If you installed MNE-Python using one of our installers, enter the above command in the Prompt.

This should display some system information along with the versions of MNE-Python and its dependencies. Typical output looks like this:

    This suggests that your environment containing MNE-Python is not active.
    If you followed the setup for 3D plotting/source analysis (i.e., you
    installed to a new ``mne`` environment instead of the ``base`` environment)
    try running ``conda activate mne`` first, and try again. If this works,
    you might want to set your terminal to automatically activate the
    ``mne`` environment each time you open a terminal::

        echo conda activate mne >> ~/.bashrc    # for bash shells
        echo conda activate mne >> ~/.zprofile  # for zsh shells

If something else went wrong during installation and you can't figure it out, check out the :ref:`advanced_setup` instructions to see if your problem is discussed there. If not, the `MNE Forum`_ is a good resources for troubleshooting installation problems.
