ModuleNotFoundError: No module named 'imageio.v3'

[David Hofmann]

Hello there,

I'm trying to get started with openpiv, so I installed it and I'm now trying to do the OpenPIV tutorial.

I have Anaconda3 installed and tried it within Spyder, Jupyter Notebook and VSC.
The import of openpiv.tools doenst work and gives me the following error message:

ModuleNotFoundError: No module named 'imageio.v3'

I would love to get some help on this, as I couldnt find any threads on this on the usual community sites.

Best regards

David

I vaguely remember having the same problem. If I'm not mistaken that was due to using conda install openpiv command instead of the command specified in the tutorial: conda install -c conda-forge openpiv.

But - if it matters - I use miniconda3 in the Windows console.

please run in the openpiv conda environment (or in the base, if you don't have separate environments) the

pip install imageio --upgrade

Probably this installed the previous version of imageio automatically.

you can also use conda https://imageio.readthedocs.io/en/stable/user_guide/installation.html

which version did you install of openpiv?

upgrading imageio did the trick, I had version 2.9.0 installed

I installed openpiv following the Installation instruction @ https://openpiv.readthedocs.io/en/latest/src/installation_instruction.html

with  conda install -c conda-forge openpiv

I'm not used to working with prompts and relatively new to programming in general, except for working with numpy and matplotlib.

If you have any introductory tips for openpiv like the tutorial, let me know :)

Thank you for the quick response!

Hi,

i'd suggest to learn by examples

https://openpiv.readthedocs.io/en/latest/src/tutorial1.html

https://github.com/OpenPIV/openpiv-python-example

https://github.com/OpenPIV/openpiv-python-examples/tree/main/notebooks

clicking on any notebook would show on github the preview

clicking on the launch binder would open a ready to run machine https://mybinder.org/v2/gh/openpiv/openpiv-python-examples/main
