NumpySocket

GitHub Sponsor

About

Provides a subclass of socket.socket that enables a TCP/IP socket that can send and recieve Numpy arrays with the same interface as a regular Python socket.

Methods

The subclass of socket.socket provides three key method overrides. All other socket methods are untouched.

  • sendall - takes a Numpy array as an argument to send an Array
  • recv - outputs a Numpy array (len() == 0 if no data received)

Installation

pip install numpysocket

Examples

There are two separate examples showing how to create a client and sever using a NumpySocket

Simple

./examples/Simple shows a server which closes after the client disconnects.

In terminal 1, run:

python simple_server.py 

In terminal 2, run:

python simple_client.py

OpenCV

./examples/OpenCV shows an actual usecase for this library (sending video frames). This example requires installing additional requirements (./examples/openCV/requirements.txt).

This example also shows how to create a persistent server which allows for new clients to connect after old clients disconnects.

In terminal 1, run:

python cv_server.py 

In terminal 2, run:

python cv_client.py

Kill terminal 2 and re-run the command and the server will allow for the new connection.
