Basemap causes Python's kernel to die #363

Closed khider closed 7 years ago

khider commented 7 years ago

I have several functions that use Basemap (and worked well until a week ago). Not everytime basemap is called, the kernel in iPython (Jupyter Notebook or Spyder).

In a terminal, I get the following error:

//anaconda/lib/python3.5/site-packages/numpy/core/fromnumeric.py:2909: RuntimeWarning: Mean of empty slice. out=out, **kwargs) //anaconda/lib/python3.5/site-packages/numpy/core/_methods.py:80: RuntimeWarning: invalid value encountered in double_scalars ret = ret.dtype.type(ret / rcount) GEOS_ERROR: b'IllegalArgumentException: Points of LinearRing do not form a closed linestring' GEOS_ERROR: b'Shell is not a LinearRing' Segmentation fault: 11

A Mac. The problem was solved when installing through conda

Yeah, there are any number of reasons why the python kernel would die. Without more information, it would be difficult to pin down the cause of the problem.

I am glad you figured out a work-around, though!
