Unable to install numexpr-1.3.1 on Mac OSX v 10.6.4 about numexpr HOT 5 CLOSED

From [email protected] on July 30, 2010 19:18:10

Here is an update of my efforts.

I installed the optional XTools package to get the GCC compiler, which seems to have fixed the "gcc-4.0: command not found" error. I ran "python setup.py build" again and encountered a new error message given below. Afraid I'm getting out of my depth here.

Update # 3:

I looked around for a stdarg.h file on my hard drive and found some, and copied the most recent (about a year old) into Developer/SDKs/MacOSX10.4u.sdk/usr/include/. I was then able to run python setup.py build, followed by python setup.py install, without error.

Unfortunately, when running the recommended test ("import numexpr; numexpr.test()") I got the following error.

Markm-Mac:numexpr-1.3.1 markhmoulton$ python -c "import numexpr; numexpr.test()"
Traceback (most recent call last):
File "", line 1, in
File "numexpr/init.py", line 14, in
from config import show as show_config, get_info
ImportError: No module named config

The config module does exist -- /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/numexpr-1.3.1-py2.6-macosx-10.3-fat.egg/numexpr/config.py. And I would expect Python to find it on its search path. I haven't figured out yet why it does not.

So I guess my question has reduced to "How can I get the init file in /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/numexpr-1.3.1-py2.6-macosx-10.3-fat.egg/numexpr/ to recognize the config module sitting next to it?"

That's strange. Where are you running the tests from?

Can you delete all the directory /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/numexpr-1.3.1-py2.6-macosx-10.3-fat.egg, re-compile, and re-install again? Please run the test suite from outside numexpr sources dir, just in case.

Luck!

I really appreciate your getting back to me.

Looks like the problem is solved. I didn't delete and re-install. I just changed where I was running the test file from. The Python docs seemed to say that setup.py should be run from inside the unzipped package folder, which I had put in the Applications directory in my Mac. That's where I ran build, install, and the "import numexpr; numexpr.test()" commands. When I instead ran it from my usual working python scripts directory, the test ran fine and I am now able to import numexpr. I assume that running the test module from the Applications directory is tantamount to running it from inside the package, which I gather is not allowed in Python 2.7 and up, though I am pretty confused by Python relative/absolute import behavior in packages and probably have it wrong.

So to sum up, my Mac install ran into three glitches: a) a missing gcc compiler, which required installing XTools; b) a missing stdarg.h file, which required copying another into the requisite folder; c) running from inside the Applications directory instead of outside. I have no idea whether other Mac users would encounter similar issues but thought you might like to know. Anyway, it runs and I'm in heaven.

Thanks again for responding and for your important software.

Here is the printout before and after I ran from my Py_Scr directory. (I added the "Yes, this is the test module" comment to the tests/test_numexpr.py module as a confirmation.)

Yes, this is the test module.

Yeah, there are always quirks derived from running the test suite right straight at the installation directory. To be frank I don't know why is this, but at least your experience could help other users visiting this.

Closing the ticket.

Status: Done
