[monviso]

I am getting unsuccessful installation running pip install pybgs on Windows in a conda environemt. this is the output I get. I am quite new to this, so thanks for any suggestion.

Hello @monviso ,

Compiling the bgslibrary on windows requires some preliminary steps, please see the links below:

• https://www.youtube.com/watch?v=896Sg-4EiZE
• https://github.com/andrewssobral/bgslibrary/wiki/Installation-instructions---Windows

You need a few requirements like:

• MSVS2019 (https://learn.microsoft.com/en-us/visualstudio/releases/2019/release-notes)
• Cmake (https://cmake.org/download/)
• OpenCV 3 or 4

You should install the OpenCV library (https://opencv.org/releases/) , then configure the env var OpenCV_DIR, see some info below:

Ps.: you may need to update some PATHs to match your environment)

git clone --recursive https://github.com/andrewssobral/bgslibrary.git
cd bgslibrary

call "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvars64.bat"

set OpenCV_DIR=C:\OpenCV\opencv-3.4.7\build
set BUILD_DIR=build_win_ocv347

set PATH=%PATH%;%OpenCV_DIR%\x64\vc15\bin
set PYTHONPATH=%PYTHONPATH%;%OpenCV_DIR%\python\cv2\python-3.7

if exist %BUILD_DIR% (
  echo Removing existing folder
  RMDIR /Q/S %BUILD_DIR%
)
mkdir %BUILD_DIR%
cd %BUILD_DIR%

cmake -DOpenCV_DIR=%OpenCV_DIR% -G "Visual Studio 16 2019" ..
:: If you want the Python Wrapper
:: cmake -DOpenCV_DIR=%OpenCV_DIR% -DBGS_PYTHON_SUPPORT=ON -DBGS_CORE_STATIC=ON -G "Visual Studio 16 2019" ..
:: The Python package will be generated at %BUILD_DIR%\pybgs.cp37-win_amd64.pyd
:: You also need to add it in your PYTHONPATH.

devenv bgslibrary.sln
cd ..

I just upgraded pybgs from pybgs-3.3.0.post0 to pybgs-3.3.0.post2 and the error seems to be fixed. Can you check please?

Thank you
