I found the problem.
-
I had to downgrade to Cython 0.21 (This is the main reason for the error)
-
Subsequently I got another problem as the script was not generating anything despite not throwing any errors. The solution had to be in this directory before executing it.
eg:.
RUN source /home/ubuntu/canonicaliser_api/venv/bin/activate && cd /home/ubuntu/canonicaliser_api/canonicaliser/cython_extensions/ && python setup.py build_ext --inplace
The painful part of Docker feels like you have to cling to all the commands as they seem to be stateless.
