[Neuroimaging] mayavi issue with pysurfer

[Christophe Pallier]

Dear all,

When I call  add_overlay() on a Brain object (as in the first example
script from pysurfer's documentation), I get the following error:

Exception occurred in traits notification handler for object:
<mayavi.core.lut_manager.LUTManager object at 0x7eff48276110>, trait:
data_range, old value: [0. 1.], new value: [ 1.e+299 -1.e+299]
Traceback (most recent call last):
  File
"/home/cp983411/anaconda3/envs/neuroimaging/lib/python3.7/site-packages/traits/trait_notifiers.py",
line 340, in __call__
    self.handler(*args)
  File
"/home/cp983411/anaconda3/envs/neuroimaging/lib/python3.7/site-packages/mayavi/core/lut_manager.py",
line 434, in _data_range_changed
    assert value[0] <= value[1]
AssertionError

Any idea?
