Temporalis library in brightway2.5 AttributeError: 'NoneType' object has no attribute 'get'

Question

I downloaded temporalis library to brightway from terminal. During installation it gave a warning that not all packages could be installed. The error is as follows:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed.(https://i.stack.imgur.com/wtVhl.png)his behavior is the source of the following dependency conflicts.
brightway2 2.4.2 requires bw2calc==1.8.1, but you have bw2calc 2.0.dev16 which is incompatible.
brightway2 2.4.2 requires bw2data<3.99, but you have bw2data 4.0.dev33 which is incompatible.

and here the screenshots from the jupyter-lab for the error code

code 1

code 2

but since Temporalis works, I tried to get a result for my project using the codes in the following link

"https://github.com/brightway-lca/from-the-ground-up/blob/main/temporal/1%20-%20Introduction.ipynb"

on github, but then the first error I got said that brightway2.5 is compatible with Temporalis, so I installed an environment with the new brightway2.5 on anaconda and tried again. Then jupyter-lab suggested me to migrate projects in another error, I applied it as well, but I still get an error like this in the line 10. do you know why and how to solve this? any help would be appreciated.

projects.migrate.project_25() error

Answer 1

You need to run the function :)

Not:

[3] projects.migrate_project_25

But:

[3] projects.migrate_project_25()

If this doesn't work, the best alternative is to create a new project and re-import your data. I think you could also try to make sure that projects.dataset.data has the correct form:

projects.dataset.data = {}
projects.dataset.save()

And then try to run projects.migrate_project_25()

And since you are in 2.5, don't do this:

[6] activity_name = 'copy_Köck building'

[7] my_activity = [x for x in ei if x['name'] == activity_name][0]

But instead:

my_activity = bd.get_node(database="thesis  0.1", name='copy_Köck building')
