"""Structured error classes in TVM.
|
|
|
|
Each error class takes an error message as its input.
|
|
See the example sections for suggested message conventions.
|
|
To make the code more readable, we recommended developers to
|
|
copy the examples and raise errors with the same message convention.
|
|
|
|
.. note::
|

Please also refer to :ref:`error-handling-guide`.
