把Numba指向TBB

Question

请问有没有办法让numba找到安装在我的虚拟环境中的TBB的最新版本？默认情况下，numba发现一个过时的TBB版本，并诉诸OMP。

这是numba警告：

NumbaWarning: The TBB threading layer requires TBB version 2021 update 1 or later i.e., TBB_INTERFACE_VERSION >= 12010. Found TBB_INTERFACE_VERSION = 10003. The TBB threading layer is disabled.

尽管TBB的安装版本是：

Name: tbb
Version: 2021.5.0

Answer 1

您可以尝试将"TBBROOT“环境变量设置为安装最新TBB的路径。Numba 0.54将支持TBB 2021，请检查您的Numba版本。
