Unable to install in Python3

[prabalbansal]

/usr/local/Cellar/python/3.7.6_1/Frameworks/Python.framework/Versions/3.7/include/python3.7m/pystate.h:241:15: note: 'curexc_traceback' declared here PyObject *curexc_traceback; ^ lsh/cMinhash.cpp:19391:13: error: no member named 'exc_type' in '_ts' tstate->exc_type = *type; ~~~~~~ ^ fatal error: too many errors emitted, stopping now [-ferror-limit=] 1 warning and 20 errors generated.

It works for Python2.7 but not able to install in Python3.7.

[paralax]

i made some changes locally to get it to work in python 3.7. see if this helps.

[noamwies]

changing

USE_CYTHON = True

in setup.py also works

[nonatofabio]

changing

USE_CYTHON = True

in setup.py also works

This solutions works for python 3.7 only if you rebuild lsh/cMinhash.cpp file. On a fresh git clone, that might not happen. So we need to add force=True to the cythonize call.

extensions = cythonize(extensions, force=True)

[boriswinner]

I forked this lib with fixes for Python3 included: https://github.com/boriswinner/LSH

!rm -rf LSH && git clone https://github.com/boriswinner/LSH && cd LSH && python setup.py install import LSH Works in Colab

[LukeLIN-web]

I also meet same problem. https://github.com/boriswinner/LSH shows ModuleNotFoundError: No module named 'Cython'
