datapath.setter Failing

[richteague]

I have tried installing this following the guide and when I call pyradex.Radex() I get the following error:

/usr/local/anaconda/lib/python2.7/site-packages/pyradex/base_class.pyc in species(self, species)
    125         self._species = species
    126         try:
--> 127             self.molpath = os.path.join(self.datapath,species+'.dat')
    128         except IOError:
    129             log.warn("Did not find data file for species {0} "

/usr/local/anaconda/lib/python2.7/site-packages/pyradex/core.pyc in datapath(self)
    636     @property
    637     def datapath(self):
--> 638         return os.path.expanduser(b"".join(self.radex.setup.radat).strip()).decode('utf-8')
    639 
    640     @datapath.setter

TypeError: can only join an iterable

I tried to track down the error and it seems that radex.setup.radat is empty. I've tried with and without setting the RADEX_DATAPATH to the right files but get the same complaint.

I'm using: $ python -c "import sys, astropy, numpy; print(sys.version); print(numpy.version,astropy.version)" 2.7.13 |Anaconda 2.3.0 (x86_64)| (default, Dec 20 2016, 23:05:08) [GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.57)] ('1.14.2', u'2.0.4')

$ gfortran --version GNU Fortran (GCC) 4.8.5

I have seen this error before, and I think it's something weird about the interactions between the data types in the wrapped RADEX modules with python string vs byte types. I'll see if I can reproduce and then fix it...

[keflavich]

I can't reproduce the problem. How are you setting up RADEX_DATAPATH? I don't think that's the problem, but I don't understand what could be going wrong now either. If I look at my radex.setup.radat variable, it looks like this:

In [11]: R.radex.setup.radat
Out[11]:
array(['/', 'U', 's', 'e', 'r', 's', '/', 'a', 'd', 'a', 'm', '/', 'L',
       'A', 'M', 'D', 'A', '/', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ',
       ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ',

       ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ',
       ' ', ' ', ' '],
      dtype='|S1')

[richteague]

I've set up the RADEX_DATAPATH through the bashrc file so:

In [6]: os.getenv('RADEX_DATAPATH')
Out[6]: '/Users/rteague/PythonPackages/limepy/aux'

When I call the radex.setup.radat (when I try and call R = pyradex.Radex() I get the error above):

In [3]: pyradex.radex.radex.setup.radat
Out[3]: 
array('',
      dtype='|S120')

[keflavich]

Could you try re-installing? I don't know what went wrong, but it's something with the fortran-wrapped code, so it has to be a problem introduced at compile time. You might try some of the suggestions here: https://github.com/keflavich/pyradex/blob/master/INSTALL.rst which may (??) fix the problem?

[richteague]

I've tried with those flags and I still get the same problem.

[keflavich]

OK, has the log given you any useful clues? I'm at a loss for what's happening, unfortunately.

[richteague]

There’s nothing obviously failing in the log. I’ll try and install it on a Linux different machine (I’ve tried both Mac OS 10.12.6 and 10.11.6 with the same results).

OK, thanks. FWIW, I'm using:

$ gfortran --version
GNU Fortran (GCC) 4.9.0

which I doubt is significantly different from your version. Maybe it's some strange interaction w/Mac OS 10.11+? I'm on 10.9. Also, my working python version is:

$ python -c "import sys, astropy, numpy; print(sys.version); print(numpy.version,astropy.version)"
3.6.4 |Anaconda, Inc.| (default, Mar 12 2018, 20:05:31)

[richteague]

No luck with that install either and I'm getting the same error. Here's the output when I run the setup script, maybe you can notice something more clearly wrong? Hopefully it's just something I'm clearly missing when I'm running the setup.

I'm now trying to run f2py again from scratch, and on python2.7, I see this failure:

which is different from what's happening to you. I'm stumped; f2py works just fine when running with python3.6 for me, but I used to be able to run f2py successfully with python2.

[keflavich]

ok, I fixed that install by specifying some flags. I believe I've finally reproduced your original error.

I don't know what caused this, but it was definitely some sort of upstream change in either f2py or numpy. Strings used to be interpreted as arrays of np.dtype('S1')s, but now instead are interpreted as np.dtype('S#'), where # is the number of elements. That change actually makes the code more convenient, but still frustrating to discover.

[keflavich]

@richteague could you try installing this branch? I think I've found and fixed the issue and all of the related fallout

[richteague]

This seems to work, thanks! It looks like the fixes only work for Python 3+ so I finally got around to installing that as the problem still persists with 2.7.

Thanks again for getting this to work, it's much appreciated!

[keflavich]

OK, thanks, I'm glad it works on py3 at least. It should work on py2 too, but, as you said, it would be best to just upgrade anyway
