Image Artist - Missing Deep Learning (AI) Models reported during Image Analysis

Issue

When working with Image Artist versions including Phenologic.AI, you may encounter an error when using AI building blocks stating:

“There are no deep learning models available for segmentation.”

This indicates that Image Artist cannot locate the required Deep Learning (DL) model files.

Cause

During Image Artist upgrades, new Deep Learning models may be introduced. If the upgrade process encounters issues - such as incomplete installation, missing permissions, or file corruption - the DL model update may fail. As a result, required models may be absent from the model directory used by Phenologic.AI.

Solution

To restore the missing Deep Learning models, manually update them using the model files packaged with the Image Artist installer.

Steps

1. Navigate to the Image Artist installation directory

2. Run the Deep Learning model update script
   Execute the following command within the installation directory:

   /bin/bash update_dl_models.sh "dl_models/dl_models.zip"
    

3. Verify the models are now available
   Open the Image Analysis page within Image Artist and check that the required segmentation models appear in the Deep Learning model list for the given AI building block.

   The example below shows the Find Cells (AI) building block:
