Error while running examples.py

[sri20152]

Hello Mr. Martin.

I have been stuck with this issue when running one of the parts of the examples.py file:

import trackanimation
from trackanimation.animation import AnimationTrack

input_directory = "C:/Users/xxxxx/Desktop/Machine Learning A-Z Template Folder/GPS/example-routes/"
ibiza_trk = trackanimation.read_track(input_directory)
sant_josep_trk = ibi

za_trk.get_tracks_by_place('Sant Josep de sa Talaia', only_points=False)
sant_josep_trk = sant_josep_trk.time_video_normalize(time=10, framerate=10)

fig = AnimationTrack(df_points=sant_josep_trk, dpi=300, bg_map=True, map_transparency=0.5)
fig.make_video(output_file='filtering-by-place', framerate=10, linewidth=1.0)

OSError Traceback (most recent call last)

9 fig = AnimationTrack(df_points=sant_josep_trk, dpi=300, bg_map=True, map_transparency=0.5)
---> 10 fig.make_video(output_file='filtering-by-place', framerate=10, linewidth=1.0)

~\AppData\Roaming\Python\Python36\site-packages\trackanimation\animation.py in make_video(self, linewidth, output_file, framerate)
201 pil_image.save(buffer, 'PNG')
202 buffer.seek(0)
--> 203 pipe.stdin.write(buffer.read())
204
205 pipe.stdin.close()

OSError: [Errno 22] Invalid argument

Please suggest something. Thank you.
