way too many files have been changes, probably need to rebase or something

[mrugank-wadekar]

Hi this is my first time contributing,
The first commit files were automatically changed, should I create a new PR so I will revert those auto changed files, and only push the actual code changes in it.?
Thanks!

[mrugank-wadekar]

I've modified my branch to affect only the .py files, do let me know if there's anything more I need to do.
Thanks!

@tazarov would you mind taking a look at this one? Thanks!

[mrugank-wadekar]

Hi @tazarov , can i expect a merge with this one?

[mrugank-wadekar]

Would updating the branch help for CI Success? If not, would appreciate some guidance on this. Thanks!

[ccurme]

Thanks! For future reference, CI was held up by code formatting. Please see contribution guidelines here for how to resolve.

Left a minor comment and would welcome any follow-up PRs. If you can put together a concise ~10 line snippet for demonstration, would be worth adding it:

• To docs (by editing notebook here;
• As an integration test.

Consider explicitly spelling out the required name here ("embed_image")

Hi thanks, for merging!
Learned a lot in my first PR into langchain.
I will add a small demonstration in the docs notebook for Chroma, in a separate PR.
A quick question, I have no idea what to do when I clone the fork into my local and some 62 or so files get auto modified?
This would be really helpful, thanks!
