SyntaxError: invalid syntax (trunk_parameters.py, line 51)

[Bodata]

I have installed openalea on a windows 10 machine.

I am not a python expert.
I use Python 3.9
Installed visualea but could not get it to run with the command "visualea" as stated in the documentation.

So i went to my ......\anaconda3\envs\openalea\Scripts directory.

There i run

python visualea

I get the program started but when i try to open Demo_WeberPenn i get:

Traceback (most recent call last):

There seems to be a pull request that is not merged.

https://github.com/openalea/weberpenn/pulls

When i manualy added the diffs i got it to work, only it does not seem very stable though.
