+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.
