[Bug]: ImportError: DLL load failed while importing _multiarray_umath: The specified module was not found.

[danerlt]

Bug Description

When I run my python test code, It tips: "ImportError: DLL load failed while importing _multiarray_umath: The specified module was not found."

my code:

from llama_index.core.base.llms.types import ChatMessage, MessageRole
from llama_index.core.prompts import (
    PromptTemplate,
)

def test_template_hava_json() -> None:
    """Test partial format."""
    prompt_txt = 'hello {text} {foo} \noutput format:\n```json\n{"name": "llamaindex"}\n```'
    except_prompt = 'hello world bar \noutput format:\n```json\n{"name": "llamaindex"}\n```'
    print(prompt_txt)

    prompt_template = PromptTemplate(prompt_txt)

    prompt_fmt = prompt_template.partial_format(foo="bar")
    prompt = prompt_fmt.format(text="world")
    print(prompt)
    assert isinstance(prompt_fmt, PromptTemplate)

    assert prompt == except_prompt

    assert prompt_fmt.format_messages(text="world") == [
        ChatMessage(content=except_prompt, role=MessageRole.USER)
    ]

Version

0.10.48.post1

Steps to Reproduce

Ensure you are using Python 3.10 and that all required dependencies, especially NumPy, are correctly installed and compatible with your Python version. Here are the steps to resolve the issue:

1. Verify Python Version:

   python --version

2. Install/Update NumPy:

   pip install --upgrade numpy

3. Check for Missing DLLs: Use tools like Dependency Walker to identify any missing DLLs.

4. Reinstall Dependencies:

   pip uninstall numpy
   pip install numpy

5. Check Environment Variables: Ensure that your PATH includes directories where the required DLLs are located.

Following these steps should help resolve the ImportError related to _multiarray_umath ^[1].

Hi @danerlt, this is the (numpy-)dll curse with conda under windows ;)

There are several possibilities, e.g. reinstalling numpy (the same or another version), copying dlls, manipulating path, setting CONDA_DLL_SEARCH_MODIFICATION_ENABLE, etc.

However my recommendation: do not use conda if you are anyways installing the packages with pip. E.g. use venv (or poetry if it is a bigger project): python -m venv venv_ai venv_ai\Scripts\activate pip install llama-index
