scikit-rf import errors: numpy and collections

Question

On

1. Pop!OS 22.04
2. with anaconda
3. running Spyder from a base environment with python 3.8.18
4. using the interpreters from other environments, each with spyder-kernels 2.4.4 installed

But I cannot successfully import scikit-rf. In an environment with python 3.9.16, numpy 1.26.4, scikit-rf 0.18.1, when I do import skrf as rf I get

AttributeError: module 'numpy' has no attribute 'complex'.

In an environment with python 3.12.2, and the same numpy and scikit-rf versions, I get

AttributeError: module 'collections' has no attribute 'Sequence'

All I can find that is remotely related is this Any ideas as to what is wrong here?

Answer 1

The issue was not specifying the conda-forge channel, like the directions say: conda install -c conda-forge scikit-rf
