try another version

Latest version 5.0.1 still has the crash problem when changing existing label value to a non-existing string value.
For me,the only choice seems to be a fallback to 4.2.10

Hi you can comment this line for quick fix, it's only used to change the color of the shape

in app.py line 1075 for the version 5.0.1
in editLabel function
#self._update_shape_color(shape)

[wkentaro]

Will be fixed by v5.0.2

pip install --no-cache-dir labelme==5.0.2
