sisl.widebandSE error

[leonardedens]

With test-hubbard-open.py, and many examples, I get AttributeError: module 'sisl' has no attribute 'WideBandSE'. Looking at the documentation of sisl, the correct class to use is sisl.physics.WideBandSE instead of sisl.WideBandSE. My packages: sisl 0.10.0 py38h1b0416a_0 conda-forge python 3.8.8 hdb3f193_4 scipy 1.6.2 py38h91f5cce_0 numpy 1.19.2 py38h54aff64_0

Full error message:

You need to update sisl. 0.11.0 is out. Agreed, this should update this in the setup.py (I'll make a PR).

[sofiasanz]

Shall we close this issue then?

[zerothi]

I think so, it is a dependency issue that is cleared now.

[zerothi]

Well, actually, it would be nice if @leonardedens confirms that resolves first ;)

[zerothi]

@leonardedens is this resolved? :)

Good morning, so for me even with the updated version of sisl I get an error when I try to run the open-example. The error message is:

Could you do:

print(sisl.__version__)

[mlorenznano]

It printed 0.10.0 .

If I do conda list I see that the version is 0.11.0.dev0

[zerothi]

There is definitely a mismatch there... :)

So that is the reason.

Generally mixing conda with pip installed packages is not good. From the looks of it you installed hubbard using pip --user, and that can fix the sisl version to the installed one. So probably do pip remove sisl or something similar (not in conda env).

[mlorenznano]

I can't remember doing anything with pip :) . However I removed sisl again and again installed it with python setup.py install and now I have version 0.11.0. Thanks for the help 👍

[zerothi]

Ok, great. I'll close then. :)
