I came across this traceback while using v1.5.1-970-g950c712

Traceback (most recent call last):

AttributeError: module 'numpy' has no attribute 'string0'

np.string0 seem to be still in the souce code of matplotlib. Asking my neighbor numpy developer, he has never heard of this. I can imagine this might have ment to be np.str0.

I got that by by trying to build the docs of https://github.com/statlab/permute , trying to fix an IPython bug https://github.com/ipython/ipython/issues/8733, so I have no clue what's going in permute, or matplotlib, or numpy. Hoping to reach someone who knows.

    Looks like this originally came in in 9638f5e (JDH: Feb 16 2008).

    There is still one reference to string0 in the numpy source: https://github.com/tacaswell/numpy/blob/master/doc/summarize.py#L32

    It looks like it was part of f2py and removed from the numpy source tree in numpy/numpy@484c100 (rkern: July 2008)

    That commit did not remove string0; it only deleted files in numpy/f2py:

    It's an alias that is still added in numpy.core.numerictypes.

    It's possible that it's a Python 2-only thing with numpy.bytes0 being the Python 3 equivalent.

    It's possible that it's a Python 2-only thing with numpy.bytes0 being the Python 3 equivalent.

    That seem probable :

    $ python2
>>> import numpy as np
>>> np.string0
<type 'numpy.string_'>

     $ python3
>>> import numpy as np
>>> np.bytes0
<class 'numpy.bytes_'>

    Cool. Seems easy enough to fix on our end, then.
