HPP conda installation issue

[Dyymon]

Hello,

I was recently trying to install HPP through conda via instructions on the website however I was met with an issue. I have undergone the installation without failure but whenever I run any HPP code through python I am met with ImportError.

ImportError: /home/dyymon/anaconda3/envs/hpp/lib/python3.8/site-packages/pinocchio/pinocchio_pywrap.cpython-38-x86_64-linux-gnu.so: undefined symbol: _ZN7eigenpy9NumpyType7getTypeEv

To recreate this error one can just install HPP via the installation steps on the webpage and than just run script with

import pinocchio

My current version of pinocchio is 2.6.14, I have tried changing the version but I have been met with multiple compatibility problems while solving the environment.

@nim65s I am tagging you as we agreed

Thanks @Dyymon for the report and the tag.

I can reproduce your issue:

FROM continuumio/miniconda3

RUN conda create -n hpp -c conda-forge python=3.8 hpp-gepetto-viewer -y
SHELL ["conda", "run", "-n", "hpp", "/bin/bash", "-c"]
CMD python -c "import pinocchio; print(pinocchio.__version__, pinocchio.__file__)"

returns:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/opt/conda/envs/hpp/lib/python3.8/site-packages/pinocchio/__init__.py", line 6, in <module>
    from .pinocchio_pywrap import *
ImportError: /opt/conda/envs/hpp/lib/python3.8/site-packages/pinocchio/pinocchio_pywrap.cpython-38-x86_64-linux-gnu.so: undefined symbol: _ZN7eigenpy9NumpyType7getTypeEv

So this is not an error on your side, but on our packaging.

@ymontmarin: Do you have any clue about this issue ?

Otherwise, I'll try to debug it, but I don't have a lot of time at the moment.

pinocchio                 2.6.14           py38hac5dcfb_1    conda-forge

So I guess the issue is that the pinocchio version is too old, as it looks like we hit https://github.com/stack-of-tasks/pinocchio/issues/1935.

It looks like for packages depending on pinocchio, the fix should be something like https://github.com/conda-forge/crocoddyl-feedstock/pull/26

Hi, thank you @Dyymon for the report and @nim65s for the ping !

I think you found it, i need to propagate the change on the hpp stacks.

Will do it as quickly as possible, but I am quite on a rush until next wednesday.

[ymontmarin]

Hi @Dyymon and @nim65s I finish a deadline rush and will bee finishing the re-release this weak. I will ping you when it is done

[ymontmarin]

Hi @Dyymon and @nim65s , the release of the hpp stack with the latest Pinocchio version is complete and the conda install command on the website now works !

Let me know if it works for you

[Dyymon]

Hi @ymontmarin, I have tested it and it works! Thank you very much!
