tvm.error#

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.

LOG(FATAL) << "InternalError: internal error detail.";

# Example code in python
