Python 3.6 builds?

Question

Python 3.6 builds?

Closed this issue 7 years ago · 14 comments

In the CI for rootpy I'd like to run tests against python 3.6 where there have been some bytecode changes. Could you provide ROOT builds for 3.6?

Hi,
It is in our list. We will notify you when we realese it.

Many thanks!

Also a ROOT later than 6.04 to avoid this bug:

Thanks again!

@ndawe is the ROOT version important for you? Right now we build ROOT 5 and 6, but I don't think a version later than 6.04 is in the Anaconda Cloud.

Ah, I see. It's not critical now I suppose. No worries. I'm working on a way to patch in a __hash__ in rootpy instead.

Answer 6 · 2017-05-09T07:30:19.000Z

I will give it a try with a more recent ROOT and let you know. In the worst case I can do some black magic to cherry pick the patch for that on top of 6.04 :)

@ndawe Can you test and see if it works?

I assume this is the fix for the hash:

Hmm, rootpy fails the most basic stl tests:

Answer 9 · 2017-05-15T00:03:02.000Z

Fixed it in the meantime by applying some patches from the official ROOT repository. Enjoy the new binaries!

Answer 10 · 2017-05-15T00:12:08.000Z

Thanks a lot! I'll move our 3.4 tests up to 3.6. That must be a ROOT bug that was later fixed. 6.09/1 is ok but then 6.09/2 has another issue....

Answer 11 · 2017-05-15T00:58:51.000Z

Unfortunately there is a bus error with ROOT 6.05 in the histogram components. I'd suggest building 6.08 or 6.06 instead.

Answer 12 · 2017-05-20T16:12:06.000Z

@ndawe Do you happen to know which patch would solve the problem? I cannot compile 6.06 or 6.08, at least not without breaking backwards compatibility with glibc 2.12 (and If I did anyways, I think it would not work with your Ubuntu 12.04 CI boxes on rootpy Travis)

Answer 13 · 2017-05-23T09:06:39.000Z

@remenska Thanks for updating the conda build of ROOT to work with Python 3.6. Could you please also update root_numpy as this is one major package many data analysts may need?

Ah, you already did that! The only thing I had to do is to change the name of the package to root-numpy.

Answer 14 · 2017-05-23T18:18:42.000Z

@Kecksdose Yep it's there
Sorry the old root_numpy binaries still linger in anaconda just in case ... Maybe I should remove it :)
