Installation PySHOT

[bkev13]

I am running into some difficulties in the installation of pyshot. I followed the steps and installed eigen3, flann and LZ4 but I get this error message when I try to run "pip install ."

  cl : Command line warning D9002 : ignoring unknown option '-O3'
  shot_descriptor.cpp
  C:\Users\beyin\anaconda3\envs\lidar38_PySHOT\Lib\site-packages\pyshot\include\mesh.h(12): fatal error C1083: Cannot open include file: 'flann/flann.hpp': No such file or directory
  error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\Community\\VC\\Tools\\MSVC\\14.29.30133\\bin\\HostX86\\x64\\cl.exe' failed with exit code 2
  [end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for pyshot
Running setup.py clean for pyshot
Failed to build pyshot
ERROR: Could not build wheels for pyshot, which is required to install pyproject.toml-based projects.

Could you assist with that.

你好，我也是遇到这个问题，请问解决了吗

Hi,

It seems flann cannot be found.

It is either a problem with your system or with the instructions given that may not apply for Windows.

Is flan installed on your system? If so, where are the headers located?

I think I will publish a conda package on conda-forge so that pyshot will be generally available; I just can't guarantee when I will be able to.

Thank you for your patience.

Hi @jjerphan, I'm also having installation problems, though different. Do you have any idea how to fix it?

pip install -e . leads to:

collect2: error: ld returned 1 exit status
error: command '/usr/bin/g++' failed with exit code 1
error: subprocess-exited-with-error

System: Ubuntu, Python 3.12 (though tried with all 3.9+ also), conda environment

I have all the dependencies (I'm aware of) installed.

Thank you in advance!

You need to have a C++ compiler toolchain installed. I recommend installing the ones of conda-forge with:

mamba install -c conda-forge cxx-compiler

I am sorry, but I do not have time to make the installation of pyshot portable at the moment. 😕

[luisfpereira]

Thanks for the quick reply @jjerphan.

The problem seems to persist:

  collect2: error: ld returned 1 exit status
  error: command '/home/luisfpereira/miniconda3/envs/py12/bin/x86_64-conda-linux-gnu-c++' failed with exit code 1
  [end of output]

In any case, this is not urgent. I can wait for the portable installation.

FYI, I likely won't have time to make a portable installation of it in the coming years.
