ModuleNotFoundError: No module named 'llama_index'

...its showing module NotFounderror how to fix it??

Hey there, @sluggishthingg! Fancy seeing you here again. Hope this message finds you less sluggish than your username suggests 😜

Based on the error message you provided, it seems like Python cannot find the llama_index module. This could be due to a few reasons:

1. The llama_index package is not installed in your current Python environment. You can install it using pip:

pip install llama_index

2. If you have already installed llama_index, it might not be in your Python path. You can check your Python path by running:

import sys
print(sys.path)

If the path to the llama_index package is not in the output, you will need to add it. This can usually be done by activating the correct Python environment, or by modifying the PYTHONPATH environment variable.

3. There might be a naming conflict with another file or directory named llama_index in your current working directory. Make sure there are no such conflicts.

4. If you're using a Jupyter notebook, you might need to restart the kernel after installing new packages.

If none of these solutions work, could you provide more information about your setup? Specifically, it would be helpful to know:

• How you installed llama_index (e.g., pip, conda, from source)
• The output of pip show llama_index
• Your Python version
• Your operating system

This will help diagnose the issue further.

Regarding the similar issues in the LlamaIndex repository, there are a few that might be relevant:

• Issue #10716 suggests installing the llama-index-vector-stores-chroma package if you're using the CLI.
• Issue #8063 suggests importing VectorStoreIndex from llama_index.indices.vector_store.base instead of llama_index.
• Issue #11071 suggests copying _generic_utils.py from llama_index/core/base/llms into llama_index/core/llms as a workaround.
• Issue #11036 suggests updating the necessary packages with pip install -U llama-index-core llama-index-llms-openai llama-index-embeddings-openai.
• Issue #10730 suggests using temporary legacy imports or the command-line tool to update existing code and notebooks.

Please note that these solutions might not directly apply to your issue, but they might give you some ideas on what to try next.

Did you run pip install llama-index ?

Maybe start with a fresh venv

pip uninstall llama-index # Remove any global install
python -m venv venv
source venv/bin/activate
pip install llama-index

isn't happening with fresh env

ModuleNotFoundError: No module named 'llama_index'
iam also facing the same issue but it shows llama_indexa after running the command pip list
But when i run the code
from llama_index import VectorStoreIndex, SimpleDirectoryReader, ServiceContext
from llama_index.llms import HuggingFaceLLM

it is showing the error:
ModuleNotFoundError: No module named 'llama_index'

[ashmalvayani]

One error that I had at my end was my file name was "llama_index.py" and when I tried to import from llama_index.llms etc, it would do a circular import and throw this error. Change your file name and it works fine.

Thanks for the tip!

you mean i need to download the py file of llama_index

[ashmalvayani]

There's no need to download anything. I made a custom python file through which I was running my code. The name of that file was "llana_index.py", I just changed the name of that file and it worked for me.
