Route import error

Discussed in #424

^{Originally posted by robhaslinger September 20, 2024}
New to semantic router and was trying to get the local execution example working, e.g. https://github.com/aurelio-labs/semantic-router/blob/main/docs/05-local-execution.ipynb

I pip installed like so on my Ubuntu box: pip install -U "semantic-router[local]"

I can not even import the Route class. that is, if I simply do this in a jupyter notebook

from semantic_router import Route

I get this error trace

{

}

I did check that cohere is installed in my virtualenv cohere=5.9.4

Any ideas are appreciated - thx Rob

[robhaslinger]

looking more carefully this seems to be the same as this issue: #422

I do wonder why cohere is needed at all for local routing using huggingface encoder or other local encoders?

[jamescalam]

we include openai and cohere as default APIs with the library so people can just pip install semantic-router and use it without issue. In any case, the problem here is due to a change in the Cohere API, we are reviewing a fix raised in #430 and will have this resolved asap

[robhaslinger]

Thanks for jumping on this. Much obliged.

[jamescalam]

Fixed in #430 #431 and new release created with the changes (0.0.67) https://github.com/aurelio-labs/semantic-router/releases/tag/v0.0.67

[jamescalam]

we noticed a bug, yanking release 0.0.67 and releasing 0.0.68 #433 - will be merged and released soon
