ERROR: Cannot install deepeval==1.4.1 and instructor==1.6.2 because these package versions have conflicting dependencies.

The conflict is caused by:
    deepeval 1.4.1 depends on tenacity~=8.4.1
    instructor 1.6.2 depends on tenacity<10.0.0 and >=9.0.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

The latest version of Tenacity made a breaking change to the statistics attribute. I did a quick search in deepeval and couldn't find an obvious usage of that attribute.

Same. It could be much helpful to have a fix on that.

@stevermeister @yuriykuzin @milest I tried tenacity ^9.0.0 but it will be conflicting with langchain.

From poetry:

... because langchain (0.1.6) depends on tenacity (>=8.1.0,<9.0.0)

I think the better solution would be to downgrade instructor?

[milest]

Ah, I see. langchain==0.1.6 is a fairly old version, isn't it? The most recent release is 0.3.6.

Downgrading Instructor is definitely an option. Would another option be to require a newer version of langchain?

[yuriykuzin]

Looks like even langchain 0.3.7 still requires older tenacity 😞

And because deepeval depends on langchain (^0.3.7), 
every version of llama-index-llms-langchain requires tenacity (>=8.2.0,<9.0.0).
