TypeError: annotate() got multiple values for argument 'text'

[MatteoRomiti]

When running the report.py I get:

Traceback (most recent call last):
  File "report.py", line 548, in <module>
    visual.heat_map()
  File "report.py", line 89, in heat_map
    va="top",
  File "/home/matteo/.local/lib/python3.6/site-packages/matplotlib/pyplot.py", line 2401, in annotate
    return gca().annotate(text=text, xy=xy, *args, **kwargs)
TypeError: annotate() got multiple values for argument 'text'

Any idea?
