IndexError: Too many indices when calling "gsw.SA_from_SP"

[mankoff]

The following code is causing gsw v. 3.0.2 to crash:

import gsw
gsw.SA_from_SP(27,10,-50,70)

with the error: IndexError: too many indices on line 128 of library.py: https://github.com/ocefpaf/python-gsw/blob/master/gsw/gibbs/library.py#L128

That line is performing operations on w and valid, which look like:

ipdb> print w; print valid
[[ 0.75]
 [ 0.  ]
 [ 0.  ]
 [ 0.25]]
[ True]

You said gsw 3.0.2 so you probably installed it from PyPI. If that's the case let me know your numpy version. There is a known bug with newer numpy that should be fixed in the github master repository.

If you wish to install from github try:

sudo pip install https://github.com/ocefpaf/python-gsw/zipball/master

Yes PyPI and Numpy version is 1.8.0.

And yes, installing from master branch fixes it.

Thanks for reporting.
