Eclipse pydev warning - “Debugger speedups using cython not found.”

Question

I get this warning while running a python program (some basic web automation using selenium):

warning: Debugger speedups using cython not found. Run \'\

Answer 1

On ubuntu, I needed to do the following in a terminal:

1. sudo apt-get install build-essential
2. sudo apt-get install python3-dev

I then copied the full setup path from the error in eclipse and onto my command prompt: python "/home/mark/.eclipse/360744347_linux_gtk_x86_64/plugins/org.python.pydev.core_6.5.0.201809011628/pysrc/setup_cython.py" build_ext --inplace

It finally compiled and the error message no longer appears.
