numba==0.55.0 is broken with numpy==1.19.5 on Python 3.7

See original GitHub issue

The latest numba version (0.55.0) is broken when used with numpy==1.19.5 on Python 3.7 (e.g. a colab enviroment!).

Steps to reproduce

On a x86_64 linux machine:

virtualenv -p 3.7 venv
source venv/bin/activate
pip install numpy==1.19.5 numba==0.55.0
In the python shell: import numba

Error

RuntimeError: module compiled against API version 0xe but this version of numpy is 0xd

ImportError: numpy.core.multiarray failed to import

More details

The above works fine on Python 3.8 and 3.9.
The specifc wheel pip used was numba-0.55.0-cp37-cp37m-manylinux2014_x86_64.manylinux_2_17_x86_64.whl.
Running !pip install numba==0.55.0 and then import numba in Google colab yields the same error (numpy==1.19.5 is the default here).

Hi @esc, import numba works for me in a 3.7 virtual env on my local machine now, and the relevant tests in our CI also appear to be passing too. Many thanks for fixing this so quickly!

OK, I think I see what is happening on our internal system. Will confer with @esc and see if we can get a new wheel posted next week.
