Documentation for Running Composition in Compiled Mode

[tylergiallanza]

The documentation for running a composition in compiled mode, using the Composition.run method, currently lists that you can set execution_mode=True to try different LLVM computation modes in order. This appears to be broken with my setup:

python version=3.9.6 PNL version=0.9.1.1

model.run(execution_mode=True)
---------------------------------------------------------------------------

TypeError: unsupported operand type(s) for &: 'bool' and 'ExecutionMode'

This is fixed when running model.run(execution_mode=pnl.ExecutionMode.LLVMRun). As a quick side-note, it is not clarified in the documentation for Composition.run which enum to use for specifying the execution_mode parameter: the documentation currently reads enum.Enum[Auto|LLVM|LLVMexec|LLVMRun|Python|PTXExec|PTXRun] rather than specifying the use of pnl.ExecutionMode.

Right, this needs to be updated. pnl.ExectionMode.Auto is the replacement for execution_mode=True
