adding py-earth to a conda repository

[mehdidc]

@fabianp @mblondel I think it could be nice to add py-earth to the conda repository you built for lightning in https://anaconda.org/scikit-learn-contrib. What do you think ? is there a way to access that account to upload new packages ? otherwise I can take care of compiling the code and send you the tarball if it is ok for you.

[fabianp]

Hi,

I could add you to that organization on conda so you ads packages, but I
was myself thinking of migrating to conda-forge as they take care of the
build infrastructure

Thanks @fabianp, I was not aware of conda-forge, if they take care of the build infastructure (moreover, I have seen that they support windows as well as osx and linux) then let's use it.

[jimmywan]

Any news on this front? Would like to have this available via conda. :)

[jcrudy]

I've been pretty busy with other things lately, so not much progress has been made in terms of releasing version 0.1 (which would then go on pypi and conda). It's been a long time since anyone has found a serious bug in py-earth, so probably I should just call what we now have 0.1 and release it. I'll try to do that soon. Feel free to bug me about it.

[jimmywan]

Feel free to bug me about it.

:)

[jcrudy]

Feel free to bug me about it.

:)

@jimmywan Keep up the good work! I'm going to try to get to this soon, but it never hurts to prod me further.

[jimmywan]

bump

[jcrudy]

I should have time next week! @jimmywan, if I don't update next week, feel free to bump this thread again.

[jimmywan]

Any progress? I'm still interested because I ran into problems trying to install this by hand.

I found a few links from others mentioning the same difficulties related to one of the dependencies and getting the right version of gcc (forgot which one).

[jcrudy]

@jimmywan I made some progress, but hit a snag with a bug that shows up on Windows 32 bit systems and ran out of time to work on it. I'll try to move forward soon, though. Can you describe the problems you ran into, and share any links you think are relevant?

[tomarharsh14]

bump

[onacrame]

Another bump. A conda package would be great.

[jcrudy]

Thanks for the encouragement, everyone. I've been super busy, and unfortunately am unfamiliar with enough with the process of creating a conda repo that it would probably take me at least a full day to figure out. If anyone reading this has experience with conda repos and wants to help, it would of course be welcome and appreciated. Otherwise, I'll try to get to this as soon as I can, and please feel free to keep bumping this thread to remind me.

[jameschartouni]

Is the conda package out? I am having a hell of a time trying to install this package on a Windows 10 machine. Do you have any suggestions? Can't wait to use the package. Thanks.

[jcrudy]

@jameschartouni It is not, and probably won't be for some time. If you post your errors I may be able to help with the installation.

[jameschartouni]

I cloned the repo, cd in the py-earth directory and ran 'python setup.py install' using python3. I want to refrain from pasting all the processing messages, but the final result is: Using c:\users\james\appdata\local\programs\python\python36-32\lib\site-packages
Finished processing dependencies for py-earth==0+untagged.491.gbc830fb . When I launch python3 and try to import pyearth, it fails. The only warning message is 'no files found matching 'pyearth\test\pathological_data'

[jcrudy]

@jameschartouni That's a problem I haven't seen before. Three questions:

1. When you launch python3 and try the import, are you still in the cloned repo? If so, that could be a problem. Changing to another directory might fix it or at least give a better error message.

2. Can you post the full stack trace from the error when you try to import?

3. Can you post specifics about your platform: Is it 32 bit or 64? What C compiler are you using? Are you using Anaconda or something else?

I primarily use python 2 on linux and mac, so it's entirely possible this is a bug in py-earth that I need to fix. I do test on Windows and python 3, but there are many different configurations.

[jameschartouni]

I am also using Anaconda. Trying to figure out which C compiler I am using. I normally use a mac, but am using Windows 10 for work.

[jcrudy]

@jameschartouni Do you have the package six installed? If not, you'll need to install it. I thought it was a standard module, but a quick search shows I was wrong.

[jameschartouni]

Installed package six.

from .earth import Earth

[jcrudy]

@jameschartouni I think that stack trace got cut off?

[jameschartouni]

oh sorry. this is the last line.

ModuleNotFoundError: No module named 'pyearth.earth'

[jcrudy]

@jameschartouni I suggest you uninstall the package and then reinstall. Perhaps installing without six messed you up. It seems like there could possibly be some issue with paths or with different versions of python coming into play, but I'm not sure. If you give me the full sequence of commands and output I might have a better guess.

[jameschartouni]

Deleted the pyearth folder in my users directory as well as the accompanying folder under site packages.
Cloned from git, cd into the folder. Ran setup with python 3.6.

[jameschartouni]

I could post the full install trace if you want. It is just very long.

[jcrudy]

It looks like your scipy isn't installed correctly. Are you able to use scipy? Specifically, a compiled module within scipy, scipy.linalg._fblas, is failing to load. It seems similar to this:
https://stackoverflow.com/questions/25406492/importing-scipy-or-scikit-image-from-scipy-linalg-import-fblas-import-error

[jameschartouni]

What seemed to fix it was deleting everything, installing numpy+mkl, then scipy. Thanks!

[jameschartouni]

Do you have any recommendations for how to add the pyearth package to my conda install of python?

[jcrudy]

@jameschartouni Glad it's working. I'm not sure what you mean by add it to your conda install? If you're referring to a conda environment, it should be installed in whichever one you were using when you installed it.

[Fish-Soup]

Hi any news on if py-earth has been added to conda?

cheers

[jcrudy]

@Fish-Soup @rth has generously taken charge of this, and I think might be finished or nearly finished. See the following:

conda-forge/staged-recipes#5108

#178

Also, py-earth is already on pypi and can be installed with pip install sklearn-contrib-py-earth.

[rth]

Yes, py-earth was added to conda-forge, and can now be installed with,

conda install -c conda-forge sklearn-contrib-py-earth

cf https://github.com/conda-forge/sklearn-contrib-py-earth-feedstock for more details.

[Fish-Soup]

Cheers this helped a lot. My team are setting up a conda environment and this was very helpful.

[MacYeh]

Thanks for the development on conda repo. It helps me a lot

[jens120]

would someone be so kind as to release a binary for 3.7?
I could not compile on windows with Visual C++ Build Tools. The error was cl.exe exit status 2
In the end I ended up installing the precompiled wheel from https://www.lfd.uci.edu/~gohlke/pythonlibs/

[rth]

Closing since py-earth can now be installed from conda-forge.

would someone be so kind as to release a binary for 3.7?

@jens120 #191 would need to be resolved first. Probably better a separate issue about wheels for 3.7.
