PySurfer/MNE安装报错求助：ImportError: No module named retrying（Ubuntu16.04）

Hey there, that error is super straightforward—it just means your Python environment is missing the retrying module that MNE depends on. Let's get this sorted out quickly:

• First, match your Python version to the install command
  Ubuntu 16.04 comes with both Python 2 and Python 3 pre-installed. Make sure you're using the right pip for the environment where you installed MNE:

  • If you're using Python 2 (the system default), run:
    sudo pip install retrying
  • If you're using Python 3, use:
    sudo pip3 install retrying

• Using a virtual environment? Activate it first
  If you installed MNE inside a virtual environment (which is a good practice!), don't use sudo. Instead:

  1. Activate your environment (replace your_venv with your actual environment name):
     source your_venv/bin/activate
  2. Install the module:
     pip install retrying

• Permission issues? Install for your user only
  If you get a permission error with the above commands, skip sudo and install the module just for your account:
  pip install --user retrying (or pip3 install --user retrying for Python 3)

Once you've installed retrying, try importing MNE again—it should work without that error now.
