Make sure you've completed the following steps before submitting your issue -- thank you! You can remove this template text afterward.
- Check if your question has already been answered in the FAQ section.
- Make sure you've read the documentation. Your issue may be addressed there.
- If those resources didn't help and you only have a short question (not a bug report), consider asking in the Gitter chat room.
- If you have a genuine bug report or a more complex question which is not answered in the previous items (or not suitable for chat), please fill in the details below.
- Include a self-contained and minimal piece of code that reproduces the problem. If that's not possible, try to make the description as clear as possible.
(Provide a short description, state the expected behavior and what actually happens.)
(The code should be minimal, have no external dependencies, isolate the function(s) that cause breakage. Submit matched and complete C++ and Python snippets that can be easily compiled and run to diagnose the issue.)
