When attempting to install without nose, I receive the following error:

@LLh-lihan, @Lotus-Lian: What is the name of your python file? If it is ‘pyod.py’, rename it. In this case you are importing your own script.

Make sure that python file name is not pyod.py. if package name and file name are same, will face this kind of error.

The issue you saw is specific to the virtual env Qt problem on mac, which is caused by matplotlib, and it is a lingering issue. The problem can be reproduced by: import matplotlib.pyplot as plt It throws error if you install the matplotlib with pip command in a mac conda virtual env… There are several fixes though.

Workaround 1: “conda install matplotlib” first
Workaround 2: https://stackoverflow.com/questions/29433824/unable-to-import-matplotlib-pyplot-as-plt-in-virtualenv

Using workaround 1, I managed to install pyod in mac virtual env and also succeeded in running examples. See the screenshot below:

To facilitate the installation, I also removed the use of matplotlib in the code (I do not remove it from dependency since example codes still need it) and publish a new version 0.5.2. You may want to give it a shot…

Let me know if the problem persists.
