How to run from modified source?

[kerryz]

Thanks for an excellent LDA implementation in Cython.

I'm developing a model that extends the LDA-model and thus I need to modify the source code in this package and then run it straight from my locally modified source code. However, when trying to import the package lda from the source directory, I run into the same problem as #25 "ImportError: No module named _lda" (I'm also using Ubuntu 14.04).

What would the best approach be to run a locally modified version of this package?

If you're willing to work in the source directory you could try

make cython
python setup.py build_ext --inplace

The import problem should go away.

Yes, this solves the issue, thank you!

I can build this inplace on one of my computers, on the other one, however, I get

$ python setup.py build_ext --inplace
ERROR:root:Error parsing

The computer that successfully builds it has pbr version 0.10.7, but downgrading pbr didn't solve the issue either. Any ideas @ariddell or is it pbr's problem?

Any idea what "Errno 5" means?

According to the Python docs the error integer value is borrowed from linux errno. 5 is simply I/O error

$ errno 5
EIO 5 Input/output error

which isn't very specific...

Closing this issue for now.
