Anthropic module is required when not using it

[Atharv24]

Hi, I added pipecat flows to my existing pipecat-ai workflow. I am using Silero, Deepgram, OpenAI and Daily for my project.

After installing pipecat-ai-flows, i tried running an example but got an import error for Anthropic.

Hey @Atharv24, do you mind sharing repro steps? I just tried the following and it worked fine.

1. Create a new venv:

python3 -m venv venv
source venv/bin/activate

2. Install pipecat:

pip install pipecat-ai

3. Create an .env file containing Deepgram, OpenAI, and Daily keys:

touch .env

4. Install pipecat extras for Daily, OpenAI, Deepgram, and Silero:

pip install "pipecat-ai[daily,openai,silero,deepgram]"

5. Install Pipecat Flows:

pip install pipecat-ai-flows

6. Created and installed dev-requirements.txt from Pipecat (link):

touch dev-requirements.txt
pip install -r dev-requirements.txt

7. Installed python-dotenv (This should be in the dev-requirements for Pipecat. I'll add that in a PR):

pip install python-dotenv

8. Ran this foundational example: https://github.com/pipecat-ai/pipecat/blob/main/examples/foundational/07c-interruptible-deepgram.py.

touch test.py

Pasted contents from 07c

python test.py

This ran as expected without needing Anthropic.

Can you share your steps?

@markbackman i was using pipecat-ai in my existing project, then added pipecat-ai-flows without any optional dependencies (as they were included in pipecat-ai dependencies)
Then i got the missing module error for Anthropic.

Thanks @Atharv24. That makes sense. I'll fix this. Working on it here: #69.

Closing this issue as #69 has been merged. This will be included in the next Flows release.
