Synda support for python3 #111

Closed durack1 closed 3 years ago

durack1 commented 5 years ago

Hi folks, I've just installed the synda v3.9 rpm on a RHEL6.10 machine. I was following the guidance at http://prodiguer.github.io/synda/sdp/rpm_install.html - with rpm updates

yum install http://sd-104052.dedibox.fr/synda/sdt/rpm/synda-3.9-1.x86_64_centos67.rpm

It seems that when I try an follow the 3.8 bugfix note (https://github.com/Prodiguer/synda/blob/master/sdt/doc/rpm_install.md), however it seems that I'm hitting errors with python2.6

[~]$ sudo /usr/share/python/synda/sdt/bin/pip install --trusted-host pypi.python.org myproxyclient==2.1.0
DEPRECATION: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of pip will drop support for Python 2.6

Is there a python3 supported version of Synda that can be installed so such issues don't occur?

I use /usr/share/python/synda/sdt/bin/python2.7

durack1 commented 5 years ago

@painter1 thanks, did you install using the rpms, or did you undertake an install from source? (I'm guessing the latter)

durack1 commented 5 years ago

@AtefBN @glevava ping!

painter1 commented 5 years ago

Cameron Harr did the installs. So I don't know, but it was very probably from rpms.

I used rpms for scientific Linux

@durack1 Hi Paul, yes there's an issue with the myproxyclient dependency if you're running on python 2.6 and the release currently I'm working on is 2.7 exclusively. I'm choosing to go to 2.7 for now in preparation for the synda release on python 3.

durack1 commented 5 years ago

@AtefBN sounds great, let me know when you expect a new release and I'll give it a go.

Also wondering if a conda release is likely, that might reduce the overhead of *.rpm building for you guys a little?

AtefBN commented 5 years ago

@durack1 Very soon. Currently working out a few bugs. I'll let you guys know when it's live and you'll be my testers :+1: For the time being the release i'm working on is via PIP. Conda is not out of question but I think packaging via pypi should be enough since there shouldn't be conflicting dependencies and at worst it could be installed within virtualenv.

durack1 commented 5 years ago

@AtefBN sounds great! FYI, we're always a good test case as the security imposed at LLNL means certificate issues etc are an ongoing challenge, and pip distributions often just don't work. We've managed to standardize on conda for most of the packages here (e.g. https://anaconda.org/CDAT, https://anaconda.org/PCMDI/), which has worked great, and enable relatively nimble installation across a large array of linux and python2/3 environment variants.

@dnadeau4 @doutriaux1 and others here should be available to provide some conda recipe examples if you wanted to fast-track such a release

Thanks for all the work that you're doing to modernize synda. I was wondering if there are any updates regarding Python3 support. Is the Python3 branch stable/ready enough for public testing?

AtefBN commented 5 years ago

Unfortunately not yet. But I'm working full time on it currently (well as soon as I get back in office) so it shouldn't really take long for a beta version to be out.

Zeitsperre commented 5 years ago

All good. Please be sure to ping people here when the code base is "good enough" ;)

Synda works with python 3 from March'21
