Not recognizing geoprocessing_core on import

[jbrownmi88]

I'm using pygeoprocessing in a conda environment running Python 3.8 on Windows 10. Getting an error when trying to import the module

---

ImportError
Traceback (most recent call last)

The geoprocessing_core.pyx file is present, so I'm not sure why it isn't detecting it. All required packages have been installed.

@jbrownmi88 How did you go about installing pygeoprocessing into your conda environment?

The geoprocessing_core.pyx file is converted to C++ and then compiled as part of the build process, and so knowing how you built and installed the package would help determine why you're experiencing this error.

@phargogh Thanks for the quick reply. I installed pygeoprocessing by first installing the packages in requirements.txt using conda install via prompt. Then I used "pip install pygeoprocessing". These processes gave me no errors.

Interesting. Usually installing via pip puts all of the required files in the right places.

Could you provide the output of pip show pygeoprocessing here?

Could you confirm that you have a file named something like geoprocessing_core.cpython-38m-win_amd64.pyd in ~\Anaconda3\envs\pygeo\lib\site-packages\pygeoprocessing\? Are there any other .pyd files in that directory?

geoprocessing_core.cp38-win_amd64.pyd is the name of the file in that directory, there are no other .pyd files

Well that is curious, everything looks to be in its expected place. Could you try running python -v -c "import pygeoprocessing" > output.txt and attach output.txt here to the issue? This would help me to understand where python is looking for (and finding) the various parts of the pygeoprocessing package.

[jbrownmi88]

That command made a blank text doc. Not sure if the terminal output from that command is what was supposed to end up in that text doc, but I copied and pasted the terminal output into outputs.txt. output.txt

[phargogh]

Well that is strange. I don't see anything clearly out of order here.

1. Do you have pygeoprocessing's dependencies already installed?
2. What about reinstalling from source? You'll need a compiler installed, but then the following might do the trick:

   pip uninstall -y pygeoprocessing
   pip install --no-binary :all: pygeoprocessing

[jbrownmi88]

That worked! I'm able to import the package now without error.

[phargogh]

OK! Well, I'm still not sure what's going on there, but I'm glad you were able to get it up and running. Thanks for helping work through the issue with us!

[jbrownmi88]

No problem! Glad it's working, excited to try some stuff out. Thanks again.
