Model card generation fails due to image too large

[hanneshapke]

Expected Behavior

Model card generation fails due to the histogram to large.

Actual Behavior

_draw_histogram calls figure_to_base64str. The method calls fig.savefig(buf, bbox_inches='tight', format='png')

The save fails with

ValueError: Image size of 6440035x455 pixels is too large. It must be less than 2^16 in each direction.
