this is what i did:
conda create -n rasa python==3.8 #fresh install
pip3 install rasa==2.6.2
pip install pip==20.2 --user #downgrade PIP
pip3 install rasa-sdk==2.6.0 # error pip3 install rasa-sdk==2.6.0 --use-feature=2020-resolver #only a warning - maybe okay…
pip3 install rasa-x==0.40.0 --extra-index-url https://pypi.rasa.com/simple #error
pip install rasa-x==0.40.0 --extra-index-url https://pypi.rasa.com/simple
damn… @nik202 i did the whole thing again, from scratch. Still get this ‘multidict’ incompatibility. I end up with the same error on the Rasa X install:
ERROR: After October 2020 you may experience errors when installing or updating packages. This is because pip will change the way that it resolves dependency conflicts.
We recommend you use --use-feature=2020-resolver to test your packages with the new resolver before it becomes the default.
rasa 2.6.2 requires multidict<5.0,>=4.6, but you'll have multidict 5.1.0 which is incompatible.

@hgoona
pip install multidict==4.6 --use-feature=2020-resolver
It’s the nature of packages that they required compatible versions.
let me try with feature resolver…
@nik202 ok. so the multidict think with resolver worked. but then i installed rasa x again and get the same damning error: (It’s sending me in circles for the incompatibility – but why ??)
yup
