   Oops!! MY BAD! I figured out that I was intended to download the zipive of the distro, then run setup.py from the download directory... Problem is jupyter doesn't seem to know where the gdl server is. But it also sort of does...

   ~/Desktop/ISOs/00_IDL/gdl_kernel-master> jupyter kernelspec list
   Available kernels:
     gdl        /home/patti/.local/share/jupyter/kernels/GDL
     python3    /home/patti/anaconda3/share/jupyter/kernels/python3
     python2    /usr/share/jupyter/kernels/python2
   ~/Desktop/ISOs/00_IDL/gdl_kernel-master> 
   

   The GDL kernel does appear in the jupyter drop-down list of kernels, but fails to start...

   Looking at the traceback and the gdl_kernel.py:
   

   gdl_kernel/gdl_kernel.py

   Line 68 in ac8edcb

   self._executable = find_executable("gdl")

   
   this means that gdl executable cannot be found by Python. One way or another, you need to ensure that find_executable("gdl") works from within Jupyter.
