pywafo install error

[eluczko]

Hi, I was wondering if anyone could help me find out why my wafo toolbox won't install properly. It appears to be an issue with pbr. I tried installing a newer version of pbr with little success in case it was a versioning issue. Please excuse my very limited python knowledge.

When I try to load the package manually:
import sys
sys.path = ['../wafo2/pywafo-master/wafo']+sys.path
import wafo
I get
ImportError: cannot import name misc

I also got that error when I tried the pip zip version, corrected a version problem with the new scipy, and then tried to load the module.

If you have a linux machine it should be quite straight forward to compile and install the distribution. However, if you have a windows machine it is (I am sorry to say) not possible at the moment to install the complete package. The reason is that the toolchain for compiling fortran on windows is broken. If you are not using any of the fortran compiled libraries, you can download pywafo from github to a folder of your liking and do the following at the dos-prompt:

python.exe setup.py develop

you will get some warnings that some libraries are not compiled, but all the stuff that is pure python code you can run.

See also the discussion on issue #12 and #29

I'm using linux... The installation of the wafo-0.2.1.tar.gz worked well, however, it is not compatible with the newest version of scipy, and when I corrected the code so that it 'assumes' it is, I get the ImportError.

Hi,

I've created a virtual env to install pywafo.
When I clone the git master, installation goes well (except for many warnings during compilation).
However, when I try to import wafo, I get the error below.
Could you let me know which version of numpy and scipy you are using?

Thanks,
Bart

Another update.
I started from a new virtualenv, and installed wafo like it says in the readme. (Without installing numpy myself first!).

When loading wafo and running the test, that results in the error-output below. (Only the first part of the test ouput is shown, there is many more after that...)

Thanks,
Bart
