Easy memmap

Numpy Memmap easy wrapper for array manipulation

Python2/3 memmap wrapper to share arrays easily between processes in real time.

Installation

You can install easy_memmap from pip using

pip install easy_memmap

or using

pip install git+https://github.com/charlielito/easy_memmap

Numpy [d]types supported

The library accepts any type of the following supported by numpy

• np.bool
• np.int8, np.int16, np.int32, np.int64
• np.uint8, np.uint16, np.uint32, np.uint64
• np.float16, np.float32, np.float64

Usage

The program that shares the array can be

from easy_memmap import EasyMemmap
import numpy as np

m = EasyMemmap(mode="w", name="mytest")

data = np.zeros((480,640,4))
m.write(data)

And the programm that reads the array

from easy_memmap import EasyMemmap

m = EasyMemmap(mode="r", name="mytest")

data = m.read()

The name of the EasyMemmap object needs to be the same, otherwise it won't be able to find the data and it will return None
