arraymap
============
The ArrayMap library provides dictionary-like lookup from NumPy array values to their integer positions. The hash table design and C implementation is based on [AutoMap](https://github.com/brandtbucher/automap), with extensive additions for direct support of NumPy arrays.
Code: https://github.com/static-frame/arraymap
Packages: https://pypi.org/project/arraymap
Dependencies
--------------
ArrayMap requires the following:
- Python >= 3.9
- NumPy >= 1.19.5
