Getting the below error when trying to import pyqstrat. My set up as follow: macos10.15 python 3.7.3 boost-cpp 1.67.0 arrow-cpp 0.13 pyarrow 0.13

ImportError: dlopen(/Users/girishmithran/anaconda3/lib/python3.7/site-packages/pyqstrat/pyqstrat_cpp.cpython-37m-darwin.so, 2): Library not loaded: @rpath/libarrow.12.dylib Referenced from: /Users/girishmithran/anaconda3/lib/python3.7/site-packages/pyqstrat/pyqstrat_cpp.cpython-37m-darwin.so Reason: image not found

This looks like you are compiling with arrow 0.12 but running with arrow 0.13. Could you please reinstall pyqstrat and send me the output of the installation process.

Thanks

Sal

Sorry, I meant for you to uninstall and then reinstall pyqstrat so that I could see the compilation messages for the C++ code. But glad you found a workaround.

Hi Sal

Reinstalling by 'pip install pyqstrat' didn't help. I got the same Import Error. I tried installing with the .tar.gz file from PyPi which fixed the issue. Install messages for both below.
