What do to when encountering TVM Errors
|
|
=======================================
|
|
|
|
When running TVM, you may encounter an error message like:
|
|
|
|
.. code::
|
|
|
|
---------------------------------------------------------------
|
|
An error occurred during the execution of TVM.
|
|
For more information, please see: https://tvm.apache.org/docs/errors.html
|
|
---------------------------------------------------------------
|
|
|
|
Congratulations! You found this page. Below are some hints on how to interpret
|
|
these error messages and what you can do when they occur.
|
|
|
|
Where do these errors come from?
|
|
--------------------------------
|
|
|
|
This error is caused by an internal invariant being violated during TVM's
|
|
execution. On a technical level, the message is generated by the
|
|
``ICHECK`` macro, found in ``include/tvm/runtime/logging.h``.
|
|
The ``ICHECK`` macro is used in many places in the TVM code to assert
|
|
some condition is true during execution; any time the assertion fails, TVM
|
|
will exit with the error message shown above.
|
|
|
|
For more details about how errors are handled and generated by TVM, please
|
|
see `error-handling-guide`.
|
|
|
|
What should I do when I encounter such an error?
|
|
------------------------------------------------
|
|
|
|
First of all, *don't panic*. Well, you can panic, but it won't help.
|
|
|
|
The best course of action is to search the
|
|
`Apache TVM Discuss Forum <https://discuss.tvm.apache.org/>`_
|
|
for the error you are encountering, to see if this has been a problem
|
|
that others have encountered, and what the solution might be.
|
|
If this error is the result of a bug that has been fixed in a more
|
|
recent version of TVM, you may need to update to a newer version.
|
|
|
|
If you do not find an existing Discuss Forum thread about your
|
|
issue, you are welcome to start a new thread on the forum with details
|
|
on the problem. *Please* include in your posting the following key
|
|
pieces of information:
|
|
|
|
* The version of TVM you are using (e.g., the git commit hash of your source tree).
|
|
* Which hardware and operating system version you are running TVM on.
|
|
* Which hardware device and OS you are targeting for your TVM compilation.
|
|
* Details on the model, inputs, or other information about the workload, which can
|
|
be used to reproduce your problem.
|
|
|
|
Without these details it is very difficult for the TVM developers to do very
|
|
much to help you.
