No module named 'torchdyn.core'

[merdan-9]

Hi,

I installed torchdyn and ran the Quickstart code, but it occurs: "ModuleNotFoundError: No module named 'torchdyn.core'".

How should I fix it?

Thanks for your help!

Which torchdyn version was installed?

[merdan-9]

torchdyn 0.2.2.1 pypi_0 pypi

Having same issue - clean install in new conda environment; installed torchdyn 1.0 using pip. Attempting: from torchdyn.core import * fails with "No module names 'torchdyn.core'.

getting the same error.

One issue is fixed by upgrading your Python to >=3.8. Attempting to pip install torchdyn with a Python version <3.8 installs torchdyn=0.2.2.1 or a different earlier version compatible with older Python.

If that fails pip install torchdyn==1.0.0

I am using conda environment with python 3.9.1 and pip21.2.3 on Ubuntu. I did use pip install torchdyn==1.0.0 to install it. (1) I can import torchdyn, which gives torchdyn version '1.0'. (2) from torchdyn.datasets import Works well with out issue However, (3) from torchdyn.core import OR from torchdyn.core import NeuralODE throws error ModuleNotFoundError: No module named 'torchcde'

Please suggest

@Zymrael I get the same behavior as @rsrad just reported; my conda environment is using Python 3.9.5 and pip installed torchdyn version 1.0. Importing 'datasets' or '*' works, importing torchdyn.core fails.

torchcde is not installed automatically in 1.0.0 since at the time it was not available on PyPI. We have now added a direct dependency so installing torchdyn=1.0.1 will install that for you. You can also simply pip install torchcde

Closing for now as the issue seems resolved.
