# Namespace

This page describes all of the name of the reserved namespace for experiments and their specificity

## File Namespace

We have reserved some names for your files so special actions and emphasize can be done automatically on the platform when you upload them.

Here is the full list :

{% hint style="warning" %}
All the names are in lowercase
{% endhint %}

### config

This is the config file used for training with our [python training packages](/picsellia/references-1/python-training-reference.md) for Tensorflow 1 and Tensorflow 2.

### checkpoint-data-latest

This is the `data` file of checkpoints when training with Tensorflow.

### checkpoint-index-latest

This is the `index` file of checkpoints when training with Tensorflow.

### model-latest

This is the exported trained model file, it must be called that way to be deployed using Picsell.ia

## Data Namespace

We have reserved some names for what you log to Picsell.ia, it is used to emphasize the most important information in the 'Summary' section of your experiment or so we can automatically compare your experiments according to those values.

![](https://2100239547-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-M78aoA9Gcxf25O1fNjm%2F-MQlr3d2DYZoNDnkwUz_%2F-MQlvKI6C0CLysXT1YGu%2Fimage.png?alt=media\&token=71181ea6-c728-45e4-8dc3-01786152ad34)

Here is the full list : 

{% hint style="warning" %}
All the names are in lowercase
{% endhint %}

### accuracy

If you log your accuracy to Picsell.ia under this name, we will automatically display the last (or the only) value to the summary (see above).

### loss

If you log your loss to Picsell.ia under this name, we will automatically display the last (or the only) value to the summary (see above).

### train-split

It will frequently happen that you split your data between a training and a test/validation batch. If you want to visualize the repartition of the data among all your classes, you will likely log a bar chart looking like this :

![](https://2100239547-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-M78aoA9Gcxf25O1fNjm%2F-MQlvpqAjWWfiDej1W8P%2F-MQlwuVx3D6EEi7EJs4U%2Fimage.png?alt=media\&token=f614d5bc-de4b-41d1-a57c-a9e07ec00cfa)

With the following command:

```python
data = {
    'x': ['car', 'person', 'bird'],
    'y': [10, 25, 12],
    'image_list': [...]
}
experiment.log(name='train-split', type='bar', data=data)
```

By naming your data `train-split`, you will have access to a brand new tab in your experiment that allows you to dive deep in the batches from your splits and check if there appears to be no issues with your data.

The `image_list` key allows you to match each of your image with a particular set so you can explore it later in the platform. The value is a list containing the internal\_id of each picture.

### test-split

See [train-split](/picsellia/experiment-tracking/namespace.md#train-split)

### eval-split

See [train-split](/picsellia/experiment-tracking/namespace.md#train-split)

### labelmap

If you train a neural network within your experiment, you will need a label map to teach the network with your labels. To save it, we encourage you to log it that way :

```python
data = {
    '0': 'car',
    '1': 'person',
    '2': 'bus'
}
experiment.log(name='labelmap', data=data, type='labelmap')
```

Remember to set the type as '`labelmap`' so we will not try to display it in your dashboard, but we will be able to use it in the playground.

### confusion-matrix

If you log a heatmap with the name '`confusion-matrix`', it will obviously be displayed in your `logs` tab, but will also be used in the `eval` tab for the interactive evaluation visualization.

See [heatmap](/picsellia/experiment-tracking/log-your-results-to-picsell.ia.md#heatmap) for more information on the format.

### evaluation

After you train your model, you will surely perform an evaluation step. To make it easier for you to find edge-cases, compare predictions to ground-truth ... We created a dedicated tab in the experiment dashboard called `eval`.

To see how to correctly use the evaluation name, please [refer to this page of the documentation](/picsellia/experiment-tracking/evaluate-your-models.md).
