Note: Async BLS is not supported on Python 3.6 or lower due to the async keyword and asyncio.run being introduced in Python 3.7.Starting from the 22.04 release, the lifetime of the BLS output tensors have been improved such that if a tensor is no longer needed in your Python model it ...
You can write special-purpose extension modules in lower-level languages to achieve maximum performance for small, computationally intensive parts that you originally prototyped in Python. You can also use tools such as Cython and CFFIto wrap existing C/C++ libraries into Python extension modules, as...
