Trouble installing from local repo or git

[IanEisenberg]

While I can successfully install implicit via pip install implicit, I am struggling to install via git (pip install git+https://github.com/benfred/implicit.git) or locally (pip install -e [implicit loc]). In both cases I get an error related to Cython (ModuleNotFoundError: No Module named 'Cython'). Full error reproduced below.

I am using conda, but installing with pip. Cython is certainly installed. I have ensured that I am using the correct pip, have tried python -m pip install, as well as installing outside of any conda environment. Any help would be appreciated!

For context, I would like to be able to do this so that I can add functionality similar to #310

I'm guessing your Cython installation is messed up . Maybe try pip3 install Cython --upgrade ?

Alternately it looks like your running conda - and we have prebuilt conda packages up on conda-forge. The advantage here is that you won't have to build the source yourself, you can just install the package with conda install -c conda-forge implicit

Having the same problem here but with virtualenv and pip, not conda. I tried upgrading Cython pip install Cython --upgrade, but it did not work for me. I can import Cython within the same enviroment in any other file except for this one. Also tried upgrading setuptools and pep517 to see if they were the problem, I guess they weren't.

Some info about the versions I'm using in case anyone wants to know:

• python 3.6.12 (also tried with 3.8 and 3.5)
• virtualenv 20.0.17
• pip 20.0.2
• cython 0.29.21 (also tried with older versions)

I could not use random_state with train_test_split and other new functionality when I installed with pip install implicit (0.4.4), that's why I wanted to install from source too.

I am having the same issue, both using conda and pyenv, with Cython installed on both.

[benfred]

Can you try with the latest release (0.4.8) ? I've changed how Cython is bundled to hopefully fix this

[emrecncelik]

Worked for me, thank you.

[benfred]

Thanks for verifying @emrecncelik -
