I also tried the correct command for the mac ox s in terminal shell,

Jims-MacBook-Pro-2:~ Jim$


no error messages there but it is still not finding the module through

    I did use the pip command and am attempting to add the files to my

     import sys

    and that worked. I even checked to make sure the files were there 

    import sys
    print (sys.path)

    ['', '/Users/Jim/anaconda/lib/python36.zip',
    '/Users/Jim/.ipython', 'Users/Jim/Documents/illustris_python']

    the file is clearly there but when i try to do import
    illustris_python as il it still can't find the module.

Note that only shows the folder is in the path.

What does an 'ls' listing reveal as to the contents of the folder?
Is there a file called illustris_python.py? or maybe illustris_python.pyc?

    I also figured that I need to manually export to python path so i tried:
    export PYTHONPATH=$PYTHONPATH:/Users/Jim/Documents/illustris_python/
      File "<ipython-input-14-30d153a77da5>", line 1
        export PYTHONPATH=$PYTHONPATH:/Users/Jim/Documents/illustris_python/
    SyntaxError: invalid syntax

    I got invalid syntax... using a mac os x

    I tried typing in terminal open .bash_profile and telling it to
    export the python path in there like some others recommended but in
    terminal it is giving me an error message for that... it must not be
    the right command for the shell.

            Usual caveat: The tutor list is targeted at the standard library
            so any help for non standard library modules is best sought from
            the library support fora. In this case that includes the
            SciPy forum
            and any illustris one.

        Though arguably the OP's problem is an import issue, not really
        module specific.

            That having been said, I'll take a guess...

                $ mkdir Illustris-3
                $ mkdir Illustris-3/groups_135

            Are these folders in your PYTHONPATH? If not Python will not
            find them.

                import illustris_python as il
                ModuleNotFoundError                       Traceback
                (most recent call last)

        The OP cded into the new dir; I'd normally expect things to be
        found if the module was a local file/dir. However...

                For some reason the computer is not recognizing this as
                a file on my
                computer. The CCA folks says this is a coding problem
                and not an illustris
                problem. any ideas to get me past this? I may also need
                help getting
                farther into the download process.

        I just ran the OP's download command:

         wget -nd -nc -nv -e robots=off -l 1 -r -A hdf5
        --content-disposition --header="API-Key:

        This doesn't seem to download any Python code at all. It does
        get a couple of HDF files, presumably with data to work with.

        So the issue is initially that the module isn't present
        anywhere. Looking at the instructions cited
        <http://www.illustris-project.org/data/docs/scripts/>>, they
        only cover fetching som data and working; they presume the
        software is already present. I don't immediately see actual
        software installation instructions, and it is not presented in PyPI.

        Most like the OP will have to install the software directly from:


        This command:

         hg clone

        should produce an "illustris_python" in the current directory,
        and then her import command will find it.

        However, there are other prerequisites. This pip command:

         pip install h5py numpy

        seems to resolve them. The OP will need to use Python 2 because
        the module seems to rely on a relative import (for its "util.py"
