Hi @huseyin01! Can you share your ruamel.yaml version please?
You can check the ruamel version by pip show ruamel.yaml

I think this is related to #7047 which was actually supposed to be fixed in rasa 2.0.2 by increasing the minimum ruamel version.

[huseyin01]

Hi @kalkbrennerei ,
here are the versions;

ruamel.yaml==0.15.100
ruamel.yaml.clib==0.2.2

[kalkbrennerei]

@huseyin01 okay, seems like you're having some issues with your dependencies. Maybe you can create a new virtual environment and install rasa from scratch. Doing that should automatically install a compatible version of ruamel.yaml

Please let me know if that helps!

[huseyin01]

Hi @kalkbrennerei ,
I already installed rasa in a brand new virtual environment on the day that I opened this issue, and I didn't specify any version name for rasa. the installed version for RASA was 2, and all its dependencies were installed automatically. So, do you mean after installation rasa, should I reinstall "ruamel.yaml" with a specific version name?

[kalkbrennerei]

Hi @huseyin01, pip3 install ruamel.yaml==0.16.10 should also get it to work, but it's still weird that the dependencies were not installed correctly when you installed rasa.

I am unfortunately also unable to reproduce this locally and still curious why this happens. So can you please check your version of rasa again?

[huseyin01]

Hi @kalkbrennerei ,

My rasa version is rasa==2.0.2

[stefanvantchev]

Same here... how come installing rasa from scratch on brand new machine doesn't work??

[TyDunn]

@stefanvantchev Did you install it in a new virtual environment? Can you please create a new issue for your problem, where you detail the versions you are using, operating system, what error you are running into, etc?

[stefanvantchev]

Everything is brand new using GCP VMs.

What I have learned about Rasa during the last 3 months of struggles is that I cannot rely on it executing the same way between my tests, so I decide to always use a new VM for each new test... so yes... new install, new everything.
