Unable to pull stimela with the command stimela pull

[Arnab-half-blood-prince]

Hi,
I have installed the uDOCKER and stimela in a ubuntu machine with python 2.7. I just used pip install for both (check screen shots).
However, when I run stimela pull it is showing me error:

File "/home/arnab/anaconda2/bin/stimela", line 6, in
import stimela
File "/home/arnab/anaconda2/lib/python2.7/site-packages/stimela/init.py", line 30, in
Path(LOG_HOME).mkdir(exist_ok=True)
TypeError: mkdir() got an unexpected keyword argument 'exist_ok'

I believe Python 2.x is no longer supported, you need 3.5 or higher.

(I am actually surprised you didn't get any errors at the installation stage, as there is a python_requires='>=3.5' statement in setup.py.)

[bennahugo]

Yes uDocker (because of) and Python 2.x support has been removed for quite some time now. Podman, Singularity and Docker are available as back ends

How the installation ran thorugh without error is what I want to know!

[Arnab-half-blood-prince]

Check the screenshots.
I will try in python3 version then. Thanks for pointing this out

[JSKenyon]

Look at the versions - I believe it is installing the last python2 version.

[JSKenyon]

Confirmed - 1.6.2 was the last release prior to dropping python2 support. If you want to save users from this, it may be necessary to delete the packages from PyPI.

[bennahugo]

Yes this is the default intended pip behaviour. It ensures 2.x long term support. However one should really not be using 2.x in this day and age.

Hi,
I have now installed podman, buildah and then stimela in a centos machine CentOS Linux release 7.4.1708 (Core).
The error remains same when running stimela pull -p :

Traceback (most recent call last):
File "/home/Barcelona/anaconda2/bin/stimela", line 6, in
import stimela
File "/home/Barcelona/.local/lib/python2.7/site-packages/stimela/init.py", line 30, in
Path(LOG_HOME).mkdir(exist_ok=True)
TypeError: mkdir() got an unexpected keyword argument 'exist_ok'

Now I am using anaconda2. Is this problem related to that? I am unable to figure it out from the error message.

check the screen shots.

[bennahugo]

Yes. Use a virtual environment initialized as virtualenv venv3 -p python3 instead of anaconda

stimela.utils.StimelaCabRuntimeError: podman returns error code 125

This error I get after installing with python3 instead on anaconda.
I guess I need to install podman and buildah using this vertual env again.
Am I right?
Or is there something else?

[bennahugo]

It looks like your podman installation is incomplete. Can you try running an image (e.g. Ubuntu 18.04) outside of stimela just to check that it runs through?

Hi all,
It is done.
I have installed docker and via docker I pulled stimela and it worked.
I guess there was a problem with podman in centos machine.

Thanks for the help.
