Hi all,
An idea: what if you shipped a working python venv as tgz with the toolflow?
Cheers,
Kaj

Hi Adam,
The screen capture of ../casper-venv/lib64/python3.5/site-packages is attached.
When I opened the test_snap.slx, I got several
"Warning: did not properly cleanup after previous model termination"
errors. Maybe there are some leftovers in hidden dirs from the previous
incarnation of the Ubuntu system (homedir is not destroyed). I of course
removed all visible files and dirs... I think this is not related to the
problem below.
I then started venv in another terminal, "cd ~test", from there "source
../mlib_devel/startsg" and ran
"
/home/kjwiik/casper-venv/bin/python
/home/kjwiik/mlib_devel/jasper_library/exec_flow.py -m
/home/kjwiik/mlib_devel/jasper_library/test_models/test_snap.slx --middleware
--backend --software
"
I got unfortunately an error message and a number of deprecation warnings,
screen capture is attached.
Thanks,
Kaj

Hi Kaj,
Please can you go to your virtual environment directory:
../casper-venv/libpython3.5/site-packages and do a "ls -la". It will list all
the packages installed. There should be colorlog, lxml, numpy, odict, pip,
pkg_resources,pyaml,setuptools and yaml python packages. Please can you send me a screen
capture, thanks?
It looks like your pyyaml did eventually install correctly though at the end -
let's assume for now all is good with your virtual environment. You may be able
to continue trying to build your slx file in the toolflow now. Try the next
step.
1)
https://casper-toolflow.readthedocs.io/en/latest/src/Configuring-the-Toolflow.html
2)
https://casper-toolflow.readthedocs.io/en/latest/src/Running-the-Toolflow.html
Let me know what you get.
