# Setup

This page will outline the setup required for using Qualcomm® Genie. First, please make sure the QNN SDK
setup is done as per the instructions in `<QNN_SDK_ROOT>/docs/QNN/general/setup.html`.

## Environment setup

### Python

If using the QNN GenAiTransformer backend, also make sure to follow the Python setup found here:
`<QNN_SDK_ROOT>/docs/QNN/general/setup.html`. Also, the
[qnn-genai-transformer-composer](https://docs.qualcomm.com/doc/80-63442-100/topic/qnn-genai-transformer-composer.html#qnn-genai-transformer-composer) tool will require installation specific version of
packages as mentioned in the following table.

| Package | Version |
| --- | --- |
| transformers | 4.31.0 |
| tokenizers | 0.19.1 |
| sentencepiece | 0.1.98 |
| tiktoken | 0.7.0 |
| tqdm | 4.65.0 |

### Linux

The user environment can be set by calling the `<QNN_SDK_ROOT>/bin/envsetup.sh` script.

Open a command shell on Linux host and run:

# Replace <QNN_SDK_ROOT> with path where QNN SDK was installed
    source <QNN_SDK_ROOT>/bin/envsetup.sh
    Copy to clipboard

This will set/update the following environment variables:

> 
> 
> - QNN\_SDK\_ROOT
> - PYTHONPATH
> - PATH
> - LD\_LIBRARY\_PATH

`${QNN_SDK_ROOT}` represents the full path to Qualcomm® AI Engine Direct SDK root.

### Windows

The user environment can be set by calling `<QNN_SDK_ROOT>/bin/envsetup.ps1` script.

First, open `Developer PowerShell for VS2022` as Administrator.

Set-ExecutionPolicy RemoteSigned
    Copy to clipboard

Then, execute the following script.

# Replace <QNN_SDK_ROOT> with path where QNN SDK was installed
    > & "<QNN_SDK_ROOT>\bin\envsetup.ps1"
    Copy to clipboard

This will set/update the following environment variables:

> 
> 
> - QNN\_SDK\_ROOT
> - PATH
> - PYTHONPATH

`${QNN_SDK_ROOT}` represents the full path to Qualcomm® AI Engine Direct SDK root.
