Starting with numba 0.12 there is a namespace for types (numba.types). The numba namespace also imports these types. In this section you can find a set of basic types you can use in numba. Many of the types have a “short name” matching their equivalent NumPy dtype.

Introduction¶. Numba translates Python code into fast executing native code. In order to generate fast native code, many dynamic features of Python need to be translated into static equivalents. This includes dynamic typing as well as polymorphism. The approach taken in numba is using type inference to generate type information for the code, so that it is possible to translate into …

Oct 08, 2021 · Numba is an open source, NumPy-aware optimizing compiler for Python sponsored by Anaconda, Inc. It uses the LLVM compiler project to generate machine code from Python syntax. Numba can compile a large subset of numerically-focused Python, including many NumPy functions. Additionally, Numba has support for automatic parallelization of loops ...

Numba is designed to be used with NumPy arrays and functions. Numba generates specialized code for different array data types and layouts to optimize performance. Special decorators can create universal functions that broadcast over NumPy arrays just like NumPy functions do. Numba also works great with Jupyter notebooks for interactive ...

Numba allows its behaviour to be changed through the use of environment variables. Unless otherwise mentioned, those variables have integer values and default to zero. For convenience, Numba also supports the use of a configuration file to persist configuration settings. Note: To use this feature pyyaml must be installed.

Version 0.54.1 (7 October, 2021)¶ This is a bugfix release for 0.54.0. It fixes a regression in structured array type handling, a potential leak on initialization failure in the CUDA target, a regression caused by Numba’s vendored cloudpickle module resetting dynamic classes and a few minor testing/infrastructure related problems.

07.07.2020 · stuartarchibald commented on Jul 7, 2020. Numba could do with a custom logging level to use internally so that developers of numba can switch on logging but it doesn't impact consumers of numba with e.g. logging.DEBUG enabled. The text was updated successfully, but these errors were encountered:

Feb 28, 2018 · This is SSA related and was working in 0.48 due to a type inference quirk (basically, type of definition at highest byte offset "won"). With SSA enabled, bs multiple definition is correctly handled along with its multiple type definitions, however neither type inference or branch pruning could work out how to handle this situation.

NUMBA_DUMP_SSA¶ If set to non-zero, print out the Numba Intermediate Representation of compiled functions after conversion to Static Single Assignment (SSA) form. NUMBA_DEBUG_PRINT_AFTER¶ Dump the Numba IR after declared pass(es). This is useful for debugging IR changes made by given passes. Accepted values are:
