/* ERROR/WARNING messages:
E: Python support missing! Compile with PYTHON package installed!
UNDOCUMENTED
U: Invalid python command
Self-explanatory. Check the input script syntax and compare to the
documentation for the command. You can use -echo screen as a
command-line option when running LAMMPS to see the offending line.
U: Python invoke of undefined function
Cannot invoke a function that has not been previously defined.
U: Python variable does not match Python function
This matching is defined by the python-style variable and the python
command.
U: Cannot embed Python when also extending Python with LAMMPS
When running LAMMPS via Python through the LAMMPS library interface
you cannot also user the input script python command.
U: Could not initialize embedded Python
The main module in Python was not accessible.
U: Could not open Python file
The specified file of Python code cannot be opened. Check that the
path and name are correct.
U: Could not process Python file
The Python code in the specified file was not run successfully by
Python, probably due to errors in the Python code.
U: Could not process Python string
The Python code in the here string was not run successfully by Python,
probably due to errors in the Python code.
U: Could not find Python function
The provided Python code was run successfully, but it not
define a callable function with the required name.
U: Python function is not callable
The provided Python code was run successfully, but it not
define a callable function with the required name.
U: Could not create Python function arguments
This is an internal Python error, possibly because the number
of inputs to the function is too large.
U: Could not evaluate Python function input variable
Self-explanatory.
U: Python function evaluation failed
The Python function did not run successfully and/or did not return a
value (if it is supposed to return a value). This is probably due to
some error condition in the function.
