Python 3.6 SyntaxError in edalize

[shenki]

A colleague installed fusesoc using pip on a machine running python3.6:

Traceback (most recent call last):
  File "/home/user/.local/bin/fusesoc", line 7, in <module>
    from fusesoc.main import main

SyntaxError: invalid syntax

The fusesoc docs list 3.6 as the minimum version, but edalize CI tests against 3.7 and above. The assignment expression was added in 3.8 according to https://docs.python.org/3/whatsnew/3.8.html#assignment-expressions

This shows up in fusesoc ci: https://github.com/olofk/fusesoc/actions/runs/4634094461/jobs/8199945878

I am the colleague. I am 100% new to fusesoc and don't know what shenki's comment should tell me. I installed python3.9 (and 3.8) and made it the default version. However, fusesoc is hard-coded to use python3.6. If I try to overwrite that e.g. with python3.8 ~/.local/bin/fusesoc it still won't run:

python3.8 ~/.local/bin/fusesoc
Traceback (most recent call last):
  File "/home/buehler/.local/bin/fusesoc", line 7, in <module>
    from fusesoc.main import main
ModuleNotFoundError: No module named 'fusesoc'

I guess this is because of this: ~/.local/lib/python3.6/site-packages I played around with symbolic links etc. but couldn't get it to work. I guess I'll have to wait for someone to help me. BTW: I am running on RedHat8.2

[shenki]

Try reinstalling fusesoc with the updated python

[buehlerIBM]

I did already. I also removed ~/.local/lib/python3.6.
This all did not help.

This has been reported in edalize as well, but with no reaction: https://github.com/olofk/edalize/issues/374

[buehlems]

We could solve the problems on our side: I had changed the python version to 3.9 but not the pip version. Once I fixed that, fusesoc did work.
So it is basically a documentation problem that remains: Python 3.6 is not sufficient. I verified that 3.8 and 3.9 do work.

[dbesse]

The problematic file is not used (contains a reference to edam["top_core"] which is not defined) and is the only one using python3.8 syntax. So, I believe it would make more sense to fix or remove it instead of requiring 3.8 and calling it a documentation problem.

I believe this should be fixed with https://github.com/olofk/edalize/issues/374 . Please reopen otherwise
