Before submitting the issue

I have visited the Troubleshooting section.
I have searched among the existing issues.
I am using a Python virtual environment.
I have a fully updated virtual environment (i.e. pip install --upgrade --upgrade-strategy eager ansys-mapdl-core)

Description of the bug

  File ~\untitled0.py:33 in <module>
    from ansys.dpf.composites.composite_model import CompositeModel

ModuleNotFoundError: No module named 'ansys.dpf.composites'

getting above error while running pyansys code

Steps To Reproduce

Steps:

First I did...
Check the code from official pyansys website & copied it on Anaconda Spyder
...

And I ran the following code:

from ansys.mapdl.core import launch_mapdl
mapdl = launch_mapdl()

# Insert your code here
import ansys.dpf.core as dpf
import numpy as np

from ansys.dpf.composites.composite_model import CompositeModel
from ansys.dpf.composites.constants import Sym3x3TensorComponent
from ansys.dpf.composites.example_helper import get_continuous_fiber_example_files

Hi @kunal-3196
Since you area asking about PyDPF Composites you should really post this issue its GitHub page: https://github.com/pyansys/pydpf-composites/issues

Have you pip installed PyDPF Composites? It does not seem so...but maybe the issue is post install.

Answer 2 · 2023-02-07T19:22:11.000Z

Thanks will check on the link. Yes I've installed it, do u have the pip command incase to install latest one?

Answer 3 · 2023-02-07T21:15:41.000Z

Hi @kunal-3196

pip install ansys-dpf-composites -U

Are you using an virtual environment for Python? I've made the mistake before of installing to different Python that I meant to use. Or can you double check that it exists in the Python site packages folder. Mike

Answer 4 · 2023-02-09T04:37:42.000Z

Hi @kunal-3196

I would recommend you to check the following link regarding PyDPF-Composites:
https://composites.dpf.docs.pyansys.com/release/0.1/intro.html#installation

I would like also emphasise the importance of the activation of the correct virtual environment as @mikerife mentioned.

Answer 6 · 2023-02-20T10:38:31.000Z

That looks like an error connecting to internet. Do you allow Python to connect to internet?

Answer 7 · 2023-02-20T11:59:19.000Z

I'm transferring this issue to dpf-composite repo.

Answer 8 · 2023-02-20T17:04:29.000Z

@kunal-3196 the last error you posted definitely looks like a networking problem connecting to the Python package index, as @germa89 noted.

This could be a temporary issue, in which case simply re-trying may work.

Otherwise, you can try

ping files.pythonhosted.org

to ensure you have basic connectivity. The output should look similar to

Have you been able to successfully install other packages with pip install? In principle, there's nothing special about ansys-dpf-composites in this step.

Answer 9 · 2023-02-21T09:06:10.000Z

@roosre AFAICT this is an installation problem / question, not a bug.

Answer 10 · 2023-02-21T18:56:31.000Z

noted thanks...seems my ansys version is creating issue it works only for 2023 R1 and above as they have mentioned

Answer 11 · 2023-02-21T19:12:44.000Z

Yes, versions before 2023 R1 are not supported by PyDPF Composites.

However, this should not produce the same kind of error you were seeing. The Ansys version only comes into play when starting a DPF server, and loading the Composites plugin.

In other words,

python -m pip install ansys-dpf-composites
python -c 'import ansys.dpf.composites'

should work with any of the supported Python versions (3.7+).

Answer 12 · 2023-02-24T18:21:38.000Z

Got this error post installing

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
pyansys 2023.1.3 requires ansys-dpf-core==0.6.0, but you have ansys-dpf-core 0.7.3 which is incompatible.
pyansys 2023.1.3 requires ansys-dpf-gate==0.2.1, but you have ansys-dpf-gate 0.3.1 which is incompatible.

Answer 13 · 2023-02-25T21:05:24.000Z

This error occurs due to the pyansys meta-package (https://github.com/pyansys/pyansys). This is a collection of PyAnsys libraries, pinned to versions that are compatible. The meta-package is released once per Ansys release cycle.

Since pydpf-composites was released after the last release of this meta-package, it is not included. The ansys-dpf-core and ansys-dpf-gate are still pinned to versions older than what pydpf-composites needs.

For now, you can avoid this issue by uninstalling the meta-package:

pip uninstall pyansys
pip install ansys-dpf-composites

The packages that were originally included in the meta-package should not be uninstalled through this procedure.

From the next release of the pyansys meta-package, installing it will include pydpf-composites automatically.

Answer 14 · 2023-03-04T06:19:57.000Z

DpfVersionNotSupported: The DPF Composites plugin requires DPF Server version 5.0 (Ansys 2023 R1) or later. Your version is currently 4.0.

Thanks @greschd but seems I will have to update the version only...i m getting error have tried after running meta package commands

Answer 15 · 2023-03-06T07:22:03.000Z

Yes, that is expected since the DPF Composites plug-in doesn't support earlier versions.

On the Python side, I think the module is now working as expected. I'll close this issue, but feel free to re-open it or create a new one in case you need more help.
