I have issue with write_gif function from basic example.

Python 2.7.1
FFmpeg 3.2.4

I have no clue how to fix it.

What is your version of moviepy ?

import moviepy
print (moviepy.__version__)

[Vadimrozov]

/System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 /Users/vadimrozov/PycharmProjects/vector_art/moviepy_example.py
print (moviepy.version) = 0.2.2.13

How about this numpy version?
It didn't exist in older versions if numpy:
numpy/numpy#6163

import numpy
numpy.__version__

You can upgrade with
pip install numpy --upgrade

Thanks, it helps! But I have now another problem:

This will be fixed in the next release. Try using opt=0 in write_gif. If it doesnt work, install the version from the repo.

Thank you for help. I saved result to video file clip.write_videofile("circle.avi",fps=25,codec="mpeg4") and it's working as a charm.

The baseline predictions are the historical averages

#baseline_preds = test_features[:, feature_list.index('average')]
baseline_preds = test_features.tofeature_list().index('DiabetesPedigreeFunction')

AttributeError: 'numpy.ndarray' object has no attribute 'tofeature_list'

whats the solution?
