Python libraries import error

Question

I am fairly new to using python notebooks on Azure AI ML Studio. Facing issues with import statements, for example

from langchain.document_loaders import PyPDFLoader

gives error - ModuleNotFoundError: No module named 'langchain'

Version of Python: 3.8.5

output of "pip list"

...

langchain 0.1.0

langchain-community 0.0.10

langchain-core 0.1.8

....

What am I missing here?

Answer 1

Hi '
RSN

Let me give you a few troubleshoots

Firstly verify that you are using the correct Python environment in Azure AI ML Studio. Sometimes, there might be multiple environments, and the package may not be installed in the active environment.

also heck the Python version and make sure it matches with the version for which you installed the langchain library.

Try restarting the Python kernel. Try restarting the kernel in your Jupyter notebook or script.

Ensure that the directory containing the langchain library is in the Python path. You can print the sys.path variable in your notebook to see the current paths.

pythonCopy code
import sys
print(sys.path)

finally confirm that the langchain library is installed in the correct Python environment. You can use the following command to check installed packages:

pythonCopy code
!pip list

Verify that langchain is listed in the output.

If this helps kindly accept the answer thanks much.

Hello @RSN , thanks for sharing the reference documents. As per the blog, looks like the author have used these versions:

langchain==0.0.240

openai==0.27.8

I would suggest you to either raise a concern directly under the respective blog or here under the github issues: https://github.com/denisa-ms/azure-data-and-ai-examples/issues

Here is the github sample, check the requirements: https://github.com/denisa-ms/azure-data-and-ai-examples/blob/master/openai/app_indexer.py

I hope this helps.
