importing pyxdameraulevenshtein crashes python kernel

[gfairchild]

1.5.2 was just released, which further addresses the NumPy dependency issue. I think this should solve your problem. I'm going to go ahead and close this issue, but please let me know if you're still experiencing this problem with 1.5.2.

[gfairchild]

How did you install it? Did the pip install succeed? I haven't actually tried installing this on Windows 10 except for within the bash subsystem (which does work).

[funkindy]

I have installed it vie pip as the dependency of textdistance package (i opened an issue there but they forwarded me here). So i just did this:

pip install textdistance[extras]

to install. And it succeded.

[gfairchild]

Can you try installing pyxdameraulevenshtein by itself using pip and let me know if that works?

[funkindy]

Same crash on import after pip install pyxdameraulevenshtein on clean venv.

[gfairchild]

Would you mind creating a fresh virtual environment and installing with the following command?:

pip install --verbose pyxdameraulevenshtein

Please paste the contents of that output here so that I can get a little more insight into what's going on.

@gfairchild i created fresh venv and installed with --verbose. Got this suspicious error:

But afterall "Successfully installed numpy-1.14.2 pyxdameraulevenshtein-1.5".

[gfairchild]

Is that the complete output of pip install?

Ok, so from what I can tell right now, it looks like the error is in the installation, not the use, of pyxdameraulevenshtein. We need to figure out how to be able to get you to install this on Windows. As indicated on the readme, you need to be able to compile C code. On Linux/Macs, this is easy. Using the Bash subsystem on Windows (which I'd highly recommend checking out if you haven't already), this is easy. I've never tried it on native Windows, though. Additionally, it looks like you're using Anaconda, which I've also never used, so I'm not sure how that affects things.

https://wiki.python.org/moin/WindowsCompilers#Microsoft_Visual_C.2B-.2B-_14.0_standalone:_Build_Tools_for_Visual_Studio_2017_.28x86.2C_x64.2C_ARM.2C_ARM64.29 may be a good place to start. So, as those instructions say, try this:

1. Install Microsoft Build Tools for Visual Studio 2017.
2. pip install --upgrade setuptools
3. pip install --verbose pyxdameraulevenshtein

Let me know if that solves your problem.

After i cloned the repo and installed from source (python setup.py install) i now get all the things work good. Also there is no crash on import pyxdameraulevenshtein as well. It is good in both clean venv and any existing venv as well.

So maybe the bug is somewhere in pypi version difference?

[gfairchild]

That's certainly interesting. The PyPI version is identical to master right now. Nothing has changed. So after trying what I just suggested, you still can't install from PyPI?

[funkindy]

New scenario appeared:

1. I cleaned up all the pip cache
2. pip install --verbose pyxdameraulevenshtein. Full log of this is attached. But this time numpy was not installed as a dependency. So after import pyxdameraulevenshtein i just got ImportError: no module called numpy
3. pip install numpy v1.14.2 is installed.
4. Now everything works good.

So if my cached numpy was broken i dont get why installing pyxdameraulevenshtein from source didnt cause the issue.

Very interesting. NumPy should automatically be installed, but that's clearly not the case. In fact, I just tried it on an empty virtual environment on my PC (using the Ubuntu subsystem on Windows 10), and I can replicate what you're referring to.

I need to fix setup.py so that NumPy is properly installed by pip if it's not already there. I'm currently essentially doing what https://stackoverflow.com/a/21621689/1269634 suggests, but that's clearly not working.

[gfairchild]

I just modified setup.py a bit to actually remove some NumPy-related code that seemed to be causing various issues. I've made the decision to expect the user to explicitly install NumPy prior to installing this library. 1.5.1 is now live on PyPI. I think this will fix your issue. Can you try and let me know?
