        A PyVISA backend that implements a large part of the "Virtual Instrument Software
        Architecture" (VISA_) in pure Python (with the help of some nice cross platform
        libraries python packages!).
        
        Description
        -----------
        
        PyVISA started as wrapper for the IVI-VISA library and therefore you need to install
        a VISA library in your system (National Instruments, Keysight, etc). This works
        most of the time, for most people. But IVI-VISA implementations are proprietary
        libraries that only works on certain systems. That is when PyVISA-py jumps in.
        
        Starting from version 1.6, PyVISA allows to use different backends. These
        backends can be dynamically loaded. PyVISA-py is one of such backends. It
        implements most of the methods for Message Based communication
        (Serial/USB/GPIB/Ethernet) using Python and some well developed, easy to deploy
        and cross platform libraries
        
        .. _VISA: http://www.ivifoundation.org/Downloads/Specifications.htm
        
        
        VISA and Python
        ---------------
        
        Python has a couple of features that make it very interesting for measurement
        controlling:
        
        - Python is an easy-to-learn scripting language with short development cycles.
        - It represents a high abstraction level, which perfectly blends with the
          abstraction level of measurement programs.
        - It has a very rich set of native libraries, including numerical and plotting
          modules for data analysis and visualisation.
        - A large set of books (in many languages) and on-line publications is available.
        
        
        Requirements
        ------------
        
        - Python (tested with 3.6+)
        - PyVISA 1.11+
        
        Optionally
        - PySerial (to interface with Serial instruments)
        - PyUSB (to interface with USB instruments)
        - linux-gpib (to interface with gpib instruments, only on linux)
        - gpib-ctypes (to interface with GPIB instruments on Windows and Linux)
        
        
        Installation
        --------------
        
        Using pip:

        ------------------
        
        In 0.5.0, the Python package installed in site-packages in now called pyvisa_py
        which makes it a valid python package. This change was decided because the old name
        was causing issues with tools such as Mypy and PyInstaller.

        - fix opening some TCPIP resources PR #242
          Some instrument do not indicate that the returned packet is the last one, so
          fix the number of returned packet for a TCPIP INSTR resource.
        - add typing validation through mypy PR #238
        - use Numpy style dosctrings PR #238
