.. _testing-installation:
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.
