Problems installing pymesh

[jsll]

Hi,

I followed your recommendation on how to install pymesh but to no success

workon pd_mesh_net
pip install git+git://github.com/PyMesh/PyMesh.git@93d182c0a7cee446e89fac74033347d900054af4

This spits out a lot of errors (below you can see some)

I also tried to install it based on the instructions here https://pymesh.readthedocs.io/en/latest/installation.html but also that did not succeed.

Appreciate any help on this matter.

Best.

Hi @jsll,

Thanks for reporting the issue. I've tried reproducing it on different computers with no previous installations, but the installation went through successfully. What setup are you using (OS, python version in the virtualenv, exact CMake version)?

Also, I'm not sure if it's necessary, but did you try again after installing the system dependencies mentioned in the PyMesh documentation?

apt-get install \
    libeigen3-dev \
    libgmp-dev \
    libgmpxx4ldbl \
    libmpfr-dev \
    libboost-dev \
    libboost-thread-dev \
    libtbb-dev \
    python3-dev

Best,
Francesco

Thanks for a swift reply. The errors are indeed very strange. Everything else installes nicely except pymesh. Below are the requested information:

• cmake version 3.17.2
• Python version Python 3.6.9
• OS version: Ubuntu 18.04 Bionic Beaver

I have all the dependencies in PyMesh installed.

[francescomilano172]

Strange indeed, I tried using CMake 3.17.2 and PyMesh also installs without problems on my side. Maybe a few things to double check:

• Are you running the pip install command in a virtualenv?
• I suspect that the above are just warnings, and although I have no displayed warnings at all it could be that the actual error that breaks the build is somewhere else. Could you post the complete output?
• Just to be sure, could you try installing CMake locally instead of using the system-wide installation, and then add your local install to PATH and CMAKE_PREFIX_PATH (as in the answer here) before running pip install git+git://github.com/PyMesh/PyMesh.git@93d182c0a7cee446e89fac74033347d900054af4?

i am gonna take the chance to ask in this issue my related question. #hatersgonnahate

Does PyMesh play a huge role in the pipeline, what is it used for? (i had no look at the code so far). In the past i already had problems building PyMesh and atm i am working on a Windows machine.

best wishes

[francescomilano172]

Hi @mganglb, no, it doesn't play a huge role in the pipeline. We use PyMesh just because it avoids the need to reimplement some functions that we use to process the meshes (loading/saving, conversion to graph-like structure, etc.).

Best,
Francesco

@francescomilano172 thx a lot for the fast answer, i am gonna have a look at it on the we.
At the moment i am bound to an Windows workstation, that's why pymesh is for me kind of complicated. (Beside using docker)
