I tried logistic_mandelbrot.py on Linux today, using a fresh conda environment with python 3.7, latest version of other required packages mentioned in the README file and I received the same error message.

The error is due to an update in vispy.visuals.volume code, which no longer contains FRAG_SHADER attribute. I checked requirements.txt for the project. It indicates to use an older version of vispy (vispy==0.6.4). Downgrading it to 0.6.4 solved the issue.

I get a similar problem on the same line 446:

$ python3 logistic_mandelbrot.py
Traceback (most recent call last):
File "logistic_mandelbrot.py", line 446, in
NEW_TRANSLUCENT_FRAG_SHADER = vispy.visuals.volume.FRAG_SHADER.format(
AttributeError: module 'vispy.visuals.volume' has no attribute 'FRAG_SHADER

Running it in Linux

Sorry for the late answer. Now I installed the right python and requirements version and it works.
