Numpy

At a glance

The community member is using SimpleNodeParser and encountering an error related to the numpy library. The issue seems to be related to the numpy version 1.26, and the community members suggest downgrading to version 1.23.5 as a solution. However, the llama_index library requires a specific version of numpy, which causes the issue. The community members are working on updating the requirements to address this problem, and one of the final solutions suggested is to restart the runtime after installing llama-index to resolve the issue.

Hello, I am using SimpleNodeParser, specifically:
node_parser = SimpleNodeParser.from_defaults()
but I got this error:
AttributeError: module 'numpy.linalg._umath_linalg' has no attribute '_ilp64'

Anyone please tell me how to fix it?

It's related to numpy 1.26 version. I downgraded it to 1.23.5 and it is working for me.

@Logan M tagging you here for error reference 🙂

Hmm weird. The python reqs say the numpy version should be ^1.24.4 lol

Yep, I installed latest version of llamaindex and it installed 1.26 for numpy.

Started getting the above error

WWhiteFang_Jr

So I had to downgrade numpy

LLogan M

oh good call out. I will update the reqs

LLogan M

hmm, I tried in a fresh env, it installed 1.26.0, but it works fine 🤔

Plain Text

>>> from llama_index.node_parser import SimpleNodeParser
>>> parser = SimpleNodeParser.from_defaults()

I tried in colab, let me try again

LLogan M

ah ok I reproduced in colab

LLogan M

strange

LLogan M

seems to be due to nltk

WWhiteFang_Jr

Yep, When you run it on 1.23.5, it downloads nltk packets

LLogan M

Will play around with the reqs and get a patch release out today. Thanks for noticing this!

hmmm ok final solution -- restart the runtime after running pip install llama-index

I think because our install changes the numpy version that was originally installed (1.23.5), it causes colab to need a restart
