Cannot run impedancefitter

I installed [impedancefitter ](https://github.com/j-zimmermann/ImpedanceFitter) as follows:
```
Conda.pip_interop(true, Conda.ROOTENV)
Conda.pip("install", "impedancefitter==2.0.3")
```
If I give the command:
```
impfit = pyimport("impedancefitter")
```
I receive the error-message:
```
ERROR: PyError (PyImport_ImportModule

The Python ... and re-launch Julia.

)

I have checked the python version, it is:
```
PyCall.pyversion
v"3.9.13"
```
Which should be sufficient. Any ideas?
