ModuleNotFoundError: No module named 'vaex.hdf5'

[HajimeKawahara]

Many thanks for developing the great package! We have been using vaex in our project, ExoJAX (through radis) for the past year or so and have been plagued with the following installation error from time to time, depending on our environment.

E       ModuleNotFoundError: No module named 'vaex.hdf5'

I get this error especially with CI in github actions. Here is an example.

In my local environments, I sometimes get this error, but I have not been able to figure out in what order this error occurs when installed. Usually, removing vaex_(***) packages (using pip) and the reinstallation of vaex (using pip) solves this error. Also, It did not seem to occur when pip install vaex (4.16.0) was done first from the latest anaconda clean installation (Anaconda3-2023.03-1-Linux-x86_64).

Does anyone have a similar experience? Or could you give us some information that could give us some clues?

I was able to reproduce the error in my local environment and found that there was no vaex directory in site-packages:

shirochan:~>ls -l anaconda3/lib/python3.10/site-packages/vaex
vaex-4.16.0-py3.10.egg/                   vaex_jupyter-0.8.1-py3.10.egg/
vaex_astro-0.9.3-py3.10.egg/              vaex_ml-0.18.1-py3.10.egg/
vaex_core-4.16.1-py3.10-linux-x86_64.egg/ vaex_server-0.8.1-py3.10.egg/
vaex_hdf5-0.14.1-py3.10.egg/              vaex_viz-0.5.4-py3.10.egg/

A tentative solution is to add the manual un-installation of vaex-(***) and re-installation of vaex at the end of setup.py, although it's not smart.

import subprocess
import sys

def uninstall(package):
    subprocess.check_call([sys.executable, "-m", "pip", "uninstall", "-y", package])

def reinstall(package):
    subprocess.check_call([sys.executable, "-m", "pip", "uninstall", "-y", package])
    subprocess.check_call([sys.executable, "-m", "pip", "install", package])

uninstall('vaex-core')
uninstall('vaex-astro')
uninstall('vaex-jupyter')
uninstall('vaex-ml')
uninstall('vaex-hdf5')
uninstall('vaex-server')
uninstall('vaex-viz')

reinstall('vaex')
