Pomegranate: Pip installation issues ValueError: 'pomegranate/*.pyx' doesn't match any files

[dmmiller612]

Hello everyone,

First I wanted to say that this repo looks really well done, and I am excited about using the probabilistic models. I know that the maintainers are probably pretty busy, so I am willing to help out where it makes sense with this issue. On my mac OSX, I ran into an issue where I can't pip install pomegranate. When running both pip install pomegranate and pip install pomegranate --no-cache-dir, I get the following error:

    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>

I looked at the readme, and it mentioned demoting a couple of libraries, but that didn't seem to do the trick. Do you have any other thoughts?

EDIT:

here is my pip list in my virtual environment:

Cython (0.27.1)
decorator (4.1.2)
joblib (0.11)
networkx (1.11)
numpy (1.11.3)
pip (9.0.1)
scipy (0.19.1)
setuptools (36.6.0)
wheel (0.30.0)

[mohataher]

pip install git+https://github.com/jmschrei/pomegranate.git

After installing dependencies, this line will solve your problems. I have tested that command on OSX on both pip3 and pip.

I have updated the README file and submitted a pull request.

@dmmiller612 let me know if that suggestion solves your problems. Thanks @mohataher!

[dmmiller612]

looking now.

[dmmiller612]

Thanks a ton @mohataher ! This solved my problem

[jmschrei]

Great, thanks!

Hi @-all,
unfortunately I am facing the same problem with win 10 64x.
I am using the IDE PyCharm and Visual Studio 2017. My libs versions are:

• Cython (0.27.1)
• decorator (4.1.2)
• joblib (0.11)
• networkx (1.11)
• numpy (1.14.3)
• pip (100.1)
• scipy (1.1.0)
• setuptools (39.0.1)
• wheel (0.30.0)

But trying to update, this error message occures:

----------------------------------------

However, Pomergranate 0.8 is working.
Has anyone have a solution?
Thank you in advance!

[jkleckner]

@dmmiller612 I wonder if #406 might fix that problem?

[dmmiller612]

I was able to solve the problem using the solution above awhile ago.

[jaideepmurkute]

Thanks @mohataher ...your solution totally worked for me! and thanks @jmschrei for the amazing work with the library.

[B4marc]

Hi,
first of all, thanks for your hints! It worked out. I am actually not that familiar with environments und the cmd, but this link helped me to use the solution of mohataher. @mohataher thanks!

When I use pip install pomegranate or pip install pomegranate --no-cache-dir I am getting :

By following the instructions from here and here it seems to work now:

1. Installing building tools from here
2. git clone https://github.com/jmschrei/pomegranate
3. cd pomegranate
4. Copy rc.exe rcdll.dll from C:\Program Files (x86)\Windows Kits\8.1\bin\x86 to C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin
5. python setup.py install

Hi all, someone solved this issue?
If yes, which is the process to install the library on w10?

[alimanfoo]

Just hit this problem, trying to install pomegranate on windows (appveyor). Checking the source distribution for 0.10.0, the .pyx files are not included, only the .c files. Looking at MANIFEST.in, the .pyx files are not included there, only .pxd and .c, which is probably why the .pyx files are not ending up in the source distribution.

So if someone tries to install pomegranate on windows but doesn't have cython installed, it will probably work (build from .c), but if cython is present then it won't work (attempt to build from .pyx but .pyx are missing from source distribution).

This doesn't crop up on Linux because by default a prebuilt wheel gets installed. If you to pip install --no-binary then you get the problem reported here.

Surely the right thing to do here is add:

include pomegranate/*.pyx

...to MANIFEST.in and issue a new source release.

Happy to submit a PR to that effect.
