Issue with installation

I ran the setup.py from the recent update/changes from the output it looks like all went through correctly, however if I run “sudo python matrix_test.py” I get the following:

Traceback (most recent call last):
  File "matrix_test.py", line 8, in <module>
    import luma.led_matrix.legacy as legacy
ImportError: No module named luma.led_matrix.legacy

I also tried on another PiZero with install va PIP and received the same error/issue.

I can confirm that pip was the issue. Follow https://github.com/rm-hull/luma.led_matrix/issues/56#issuecomment-277845830 to get this running!

@mB-PiBox - as long as you’ve got a version of pip installed, it should self-update with:

$ sudo -H pip install --upgrade pip
$ pip --version
pip 9.0.1 from /usr/local/lib/python2.7/dist-packages (python 2.7)

Next, something clearly something got corrupted along the way on your RPi, so I would suggest running:

$ pip list | grep luma

Then for each luma.* package listed, uninstall it:

$ sudo -H pip uninstall luma.core 
$ sudo -H pip uninstall luma.led_matrix

And so on …

Next re-install… In theory luma.core should be installed as a dependency, but for the sake of caution, do it explicitly:

$ sudo -H pip install luma.core luma.led_matrix

Pull the latest from the git repo (I just made some fixes to the demo), and inside the project root dir:

$ git pull

And retry the demo:

$ python examples/matrix_demo.py
