Numpy

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

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!

LLogan M

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
