# Launch your Hyperparameters tuning

### 1 . Overview

Once your Scan have been well configured you will be able to visualize all the Runs created on your Scan dashboard.

Here you can see that we created a 8 runs Scan in order to find the best `learning_rate` for our training, by trying to optimize the `rmse` value of our final model. 

As no Runs have been launched for now, there are all in a `waiting` mode. 

### 2 . Visualizing the script to run 

Next to `Stop Scan`, your can see a python filename , visualize it by clicking on it, it's the python script that you chose to run for your scan.

### 3 . Initialize the CLI 

**Prerequisite :**  [**Install Picsell CLI**](https://picsellia.gitbook.io/picsellia/hyperparameter-tuning/install-picsell-cli) **:)** 

**Go on your best terminal and just type :**

```
picsell init scan YOUR_SCAN_ID
```

You can find you scan ID on the Scan page shown below

You should see this type of message 

### 4 . Launch your sweeps

```
picsell launch scan YOUR_SCAN_ID 
```

{% hint style="warning" %}
If you don't have NVIDIA gpu drivers installed on your machine, please set the -g flag to false 
{% endhint %}

```
picsell launch scan YOUR_SCAN_ID -g false 
```
