Cannot properly install Pyrosm

Hi, I can no longer install and import the library correctly.

FIRST ATTEMPT

• First I tried on my main computer, running Windows 10 version 10.0.19043 Build 19043.
• I created a virtual environment using anaconda, installed geopandas using conda install geopandas and subsequently pyrosm using conda install -c conda-forge pyrosm, as recommended in the documentation.
• The installation is successful, but when I try to import the library I get this error:
• Reinstalling anaconda did not lead to any solution.

SECOND ATTEMPT

• I then tried to recreate the problem on my laptop (still windows 10 version 10.0.19043 Build 19043).
• The same error occurs again

THIRD ATTEMPT

• So I decided not to use an Anaconda env, but a simple Python virtual env.
• Still, same error
• Even installing only via pip the problem remains

FOURTH ATTEMPT

• I created a virtual machine with Ubuntu 64bit 20.04
• Installing everything with conda (and conda-forge) leads to the same problem
• Whether using an anaconda environment or a Python env the problem remains
• Using only pip to install the packages (in a Python env), the installation and import is (apparently) successful, but when you try to run a simple piece of code, the kernel dies (see image below).

FIFTH ATTEMPT

• I finally tried to use Google Colab
• The packages correctly install via pip
• and it is possible to import them, but with the same warning obtained in Linux (as expected)

/usr/local/lib/python3.7/dist-packages/geopandas/_compat.py:115: UserWarning: The Shapely GEOS version (3.9.1-CAPI-1.14.2) is incompatible with the GEOS version PyGEOS was compiled with (3.10.0-CAPI-1.16.0). Conversions between both will be slow.
  shapely_geos_version, geos_capi_version_string

• Still, if you try to run the code the kernel dies.

PS: on the laptop I have a working environment with both Geopandas and Pyrosm, where the code runs correctly. The problem is that I can no longer replicate such an environment. Even creating a .yml file and reinstalling exactly the same packages generates the error. I have tried on multiple devices and OS, but with no success.

I have exhausted every option…

Thank you for your time, Daniele

Thank you so much for your quick answer! @HTenkanen

I installed cykhash-1.0.2 beforehand and everything works fine now 😃

I don’t know if it is possible but it would be a good idea to have this version of cykhash installed when using conda-forge.

Yes, I need to update the code base to reflect the latest changes in cykhash for the next release. But yes, freezing the cykhash version to older one is a quick fix for the installation issues.
