# Installation on Windows¶

This section describes how to install the latest available Prophesee’s Software on Windows 10 64-bit.

This guide assumes that you signed up to use our software. If not, sign up for Metavision Essentials first.

## Requirements¶

Please, note that the following requirements must be fulfilled:

• Operating system: Windows 10 64-bit

• Architecture: amd64 (a.k.a. x64)

• Graphic card: must support OpenGL 3.0 minimum

• CPU: must support AVX2 (see the list of processor supporting AVX2)

## Prerequisites¶

If you have previously installed any Prophesee’s software, you will need to uninstall it first:

1. Make sure that no Prophesee or Metavision software is running

3. Click Settings

4. Search for Apps & features via the search

5. In the list of installed programs, find any Prophesee or Metavision software and click the Uninstall button

6. Check that there is no Prophesee folder left in your Program Files folder (if still present, delete it)

## Installation¶

First, you need to install Metavision Essentials and then Python and some associated tools and libraries if they are not yet available on your machine.

Install Metavision Essentials:

• Use the installer you downloaded from the Metavision Essentials sign-up page: Metavision_Essentials_210_Setup.exe

• Run Metavision_Essentials_210_Setup.exe and follow the prompt

• If an alert message from Windows pops up during install, click more info, then run anyway

Install Python 3.7:

• Run the installer and follow the prompt. We advise you to check the box that propose to update the PATH or to update it manually with this command, replacing “Username” with your own.

C:\Users\Username\AppData\Local\Programs\Python\Python37;C:\Users\Username\AppData\Local\Programs\Python\Python37\Scripts (assuming the default install path was used)

• Edit your environment variable PYTHONPATH and append the following path (if it is not already there):

"C:\Program Files\Prophesee\lib\python3.7\site-packages" (and re-start your session)


Finally, install some Python libraries using pip:

• Open a command prompt

• Run the command:

pip install numpy opencv-python matplotlib jupyter


Warning

You can use Anaconda/Conda to install Python and manage your packages, but ensure to use Python 3.7. Other versions are not supported. In this documentation, we chose to use pip. If you wish to use Anaconda/Conda, adapt the library installation accordingly and use conda instead of pip.

## Plugins¶

If you installed a third-party vendor plugin, you also need to specify where this plugin is located by using the MV_HAL_PLUGIN_PATH environment variable. For example:

set "MV_HAL_PLUGIN_PATH=C:\path\to\my\plugins\"


Note

If you want to permanently set this environment variable, right click on your computer in the file browser and select properties. Then, click Advanced system settings in the left hand side bar and click Environment Variables. Finally, add the MV_HAL_PLUGIN_PATH variable in the System variables section.
