Solution

Problem with the above command

One needs some basic understanding to resolve this error. The command I mentioned compiles the data files too, which is not correct. The task was to compile the code using Transonic as a medium to accelerate the Python code.

Theory behind backends

• By default, Pythran is the backend of Transonic.
• It also supports numba, cython, and python.

Reason for Error

• The error is because data/input16.txt is not a Python file. The command which I used only compiles Python files.

Command to run

• For Compilation

  transonic -b numba python/compiled_methods.py

• For Execution

  TRANSONIC_BACKEND="numba" python python/compiled_methods.py data/input16.txt
