# Launching the Cognex Deep Learning Parameter Search Utility

Before launching the Cognex Deep Learning Parameter Search utility, you need to make sure that your VisionPro Deep Learning workspace is ready for the search:

- All the images in your workspace must be labeled

- The workspace must have a training Training is the process that your tool, which is a neural network, is learning about the features (pixels) based on the labels you made. For example, a tool will learn the defect/normal pixels in each image based on the defect/normal labels you drew. The goal of the tool Training is learning enough to give the correct inspection results of whether an unseen image is defective or not. The key to training is to ensure that you include all possible variations within your training set, and that your images are accurately labeled. Training times vary by the application, tool setup and the GPU in the PC being used to train the network. set with enough images

- The mode and the type of the tools in the workspace must be chosen before importing the workspace into the utility.

- Before launching the utility, you must quit Cognex Deep Learning Studio first.

To launch the utility:

- Click on the icon of the utility in the Windows Startup Menu.

- Open the utility from the C:\Program Files\Cognex\VisionPro Deep Learning\4.2\Parameter Search\ directory.
