problem with loading a filter about easygalaxy HOT 9 CLOSED

@mjvakili did you manage to get this issue sorted?

from easygalaxy.

@themiyan yes I managed to get it to work
by doing something similar to this:
model = ezgal.model("bc03_burst_0.1_z_0.02_chab.model") model.add_filter("i.dat" , "omega_cam" , units = "nm")
where "bc03_burst_0.1_z_0.02_chab.model" is downloaded from the ezgal website

@mjvakili Hi, I'm experiencing the same issue as you mentioned earlier. I tried copying your code from your recent comment, and am still getting the same error. Could you share more of your code so I have more context?

Thanks

@stewm0 It's because the vega reference spectrum is not being installed with the rest of the package. I bet the other people here are just running things from the source directory, and you are installing things with python setup.py install.

Check out https://docs.python.org/3.6/distutils/setupscript.html#installing-package-data

You can also look at my recent fork for a fix.

@stewm0 sorry I totally forgot to respond!
The code is the same. As @boada pointed out, it's most likely the package itself that's not installed properly on your machine. You might want to install it directly from the source.

@boada You're exactly right, as I eventually figured out. Thanks for the response

If installed with pip, as recommended on the EzGal website, one has to install the data file (found here) separately, as it contains some standardized information (e.g. vega spectrum).

@stewm0 Hi, I am also dealing with this problem. Where can I find the the ``data" file? I mean, that the model information is easy to download, which stored on the EzGal website. However, I couldn't find the filters information, especially the standardized vega spectrum.

It's included in the package.
