I recently installed a fresh Conda installation for VISAN. When using the wplot function with an optional size property, I received a Python exception. I have since traced the cause of the exception to a typographic error in the command.py module. There are multiple instances of a text string “wx.SystemSettings_GetMetric” (search for this text). This should be “wx.SystemSettings.GetMetric” with the underscore replaced by a dot.
After modifying the command.py module, the size property worked correctly.
