Missing imports in the pykeops v2.0b3 package (beta version)

[jeanfeydy]

Hi @joanglaunes, @bcharlier,

Unfortunately, the latest beta package seems to be broken. On Google Colab, running:

!pip install pykeops==2.0b3
import pykeops
pykeops.clean_pykeops()

fails with:

[KeOps] Compiling cuda jit compiler engine ... OK
[pyKeOps] Compiling nvrtc binder for python ... OK
[KeOps] /root/.cache/keops2.0b3/build has been cleaned.
[KeOps] Compiling cuda jit compiler engine ... OK

I assume that this can be fixed with a simple import in __init__.py, but I wonder when this bug was introduced on the main branch, and if other parts of the package were affected. What do you think?

See you soon, Jean

It is fixed now in main. Sorry about it, I think it was due to my updates two days ago (merging branch imports_fix).

Hi @joanglaunes,

Thanks! Could @bcharlier maybe release a 2.0b4 package (without forgetting to fix the keopscore version issue, if this is still needed) and I will try this as soon as possible?

See you soon, Jean

[joanglaunes]

Yes the 2.0b4 version is arriving in a few minutes...

[bcharlier]

I just upload it on pypi...

Thanks!
