alreadyinstalled, if not, install them first:Arch Linux:
Debian/Ubuntu:
Trusted Mac download pySerial 3.4. Virus-free and 100% clean download. Get pySerial alternative downloads. Pyvisa-py relies on socket module in the Python Standard Library to interact with the instrument which you do not need to install any extra library to access those resources. Serial resources: ASRL INSTR¶ To access serial resources, you should install PySerial. Version 3.0 or newer is required. No special configuration is required.
- After importing pyvisa, we create a ResourceManager object. If called without arguments, PyVISA will prefer the default backend (IVI) which tries to find the VISA shared library for you. If it fails it will fall back to pyvisa-py if installed. You can check what backend is used and the location of the shared library used, if relevant, simply.
- PyVISA includes a debugging command to help you troubleshoot this (and other things): pyvisa-info. According to National Instruments, NI VISA 17.5 is available for the following platforms. If NI-VISA is not available for your system, take a look at the Frequently asked questions.
CentOS/Fedora:
PyVISA
If you wish to use
PyVISA
to perform command-based instrument programming, getPyVISA
installed first:If you don't wish to install the stack system-wide, but only to install it inthe local user scope,
--user
flag could be appended to install
subcommandand root permission could be omitted.All python package installation follow the same guideline.
Now
PyVISA
needs a back-end to work, which you could have an option.NI-VISA
You could choose to install VISA library provided by National Instruments as theback-end of PyVISA. NI-VISA library for Linux is mainly packaged for RPM-basedLinux distributions and installation on these distributions such as CentOS,scientific Linux or Fedora would be easy.
For installation guidelines of NI-VISA, please refer to the National Instrumentswebsite.
pyvisa-py
PyVISA
provides a pure python back-end which is free and open source. One whois not able or convenient enough to install NI-VISA
should turn to this choice.pyvisa-py
relies on a number of python packages for interface communication.pyusb
For connecting to devices through USB,
pyusb
must be installed.Install

python-gpib
For connecting to devices through GPIB,
python-gpib
must be installed.This module is part of the
linux-gpib
driver, it also requires the kerneldriver to function, which could be installed through source code. Detailedinstallation guide could be found at projectsite.For Arch Linux users, this could be installed through AUR:

Previous step: Run code in the debugger
The Python developer community has produced thousands of useful packages that you can incorporate into your own projects. Visual Studio provides a UI to manage packages in your Python environments.
View environments
Pyvisa Vs Pyserial
- Select the View > Other Windows > Python Environments menu command. The Python Environments window opens as a peer to Solution Explorer and shows the different environments available to you. The list shows both environments that you installed using the Visual Studio installer and those you installed separately. That includes global, virtual, and conda environments. The environment in bold is the default environment that's used for new projects. For additional information about working with environments, see How to create and manage Python environments in Visual Studio environments.NoteYou can also open the Python Environments window by selecting the Solution Explorer window and using the Ctrl+K, Ctrl+` keyboard shortcut. If the shortcut doesn't work and you can't find the Python Environments window in the menu, it's possible you haven't installed the Python workload. See How to install Python support in Visual Studio for guidance about how to install Python.
- The environment's Overview tab provides quick access to an Interactive window for that environment along with the environment's installation folder and interpreters. For example, select Open interactive window and an Interactive window for that specific environment appears in Visual Studio.
- Now, create a new project with File > New > Project, selecting the Python Application template. In the code file that appears, paste the following code, which creates a cosine wave like the previous tutorial steps, only this time plotted graphically. Alternatively, you can use the project you previously created and replace the code.
- With a Python project open, you can also open the Python Environments window from Solution Explorer by right-clicking Python Environments and selecting View All Python Environments
- Looking at the editor window, you'll notice that if you hover over the
numpy
andmatplotlib
import statements that they are not resolved. That's because the packages have not been installed to the default global environment.
Install packages using the Python Environments window
- From the Python Environments window, select the default environment for new Python projects and choose the Packages tab. You will then see a list of packages that are currently installed in the environment.
- Install
matplotlib
by entering its name into the search field and then selecting the Run command: pip install matplotlib option. This will installmatplotlib
, as well as any packages it depends on (in this case that includesnumpy
). - Consent to elevation if prompted to do so.
- After the package is installed, it appears in the Python Environments window. The X to the right of the package uninstalls it.NoteA small progress bar might appear underneath the environment to indicate that Visual Studio is building its IntelliSense database for the newly-installed package. The IntelliSense tab also shows more detailed information. Be aware that until that database is complete, IntelliSense features like auto-completion and syntax checking won't be active in the editor for that package.Visual Studio 2017 version 15.6 and later uses a different and faster method for working with IntelliSense, and displays a message to that effect on the IntelliSense tab.
Run the program
- Now that matplotlib is installed, run the program with (F5) or without the debugger (Ctrl+F5) to see the output:
