# About This Release

As of VisionPro Deep Learning 2.1.1, Cognex offers fixes to solve some known issues in the previous versions.

- Fixed an issue that the execution of VisionPro 10.1 C# API method Cognex.Vision.Startup.Shutdown() is not completed within an expected time when using VisionPro Deep Learning Tool Block.

- Fixed an issue that the Focused tools (Blue Locate, Blue Read, Green Classify Focused, Red Analyze Focused Supervised, Red Analyze Focused Unsupervised) occasionally expose inconsistent results given exactly the same configurations.

- Fixed an issue that the processing of Blue Locate or Blue Read rarely gets slower.

  - To solve this issue, we allowed access to a new processing parameter called max_scan_iterations in the runtime API. With this parameter, you can limit the maximum search time to speed up the processing. For more details, see Breaking Changes to the API.

Note:

- The VisionPro and VisionPro Deep Learning software require that a valid Cognex Security Dongle be installed directly to PCs running the software during all phases of operation (programming, processing, training, testing, etc.). Any attempts to temporarily remove, substitute, or share a Cognex Security Dongle may cause your system to operate incorrectly, and may result in the loss of data.

  When VisionPro Deep Learning is configured for the Client/Server functionality, and a computer has been configured as a server, the Cognex Security Dongle must be attached to the server, but the client(s) does not need a Cognex Security Dongle.

- Sample code is included with the VisionPro Deep Learning 2.1.1 installer. The resources for the sample code (VisionPro Deep Learning 2.1.1 Sample Code Resource.msi), which include images and workspaces, are available for download from the Cognex Support Site.
- For more information about new API functionality in this release, see the Cognex VisionPro Deep Learning Suite .NET Library and Cognex VisionPro Deep Learning Suite C API help files.

# Introducing Cognex Deep Learning™

- VisionPro Deep Learning is Cognex’s new PC-based deep learning software product. It is the direct successor to VisionPro ViDi™. The first release of VisionPro Deep Learning adds a new “High Detail” mode to the existing ViDi Classifier, which is now known as “Focused” mode. High Detail mode was originally developed as part of the SuaKIT™ product. It provides highly accurate results for a wide range of challenging applications, while Focused mode typically trains and runs faster. In the recent release of VisionPro Deep Learning, a new mode called "High Detail Quick" is added, offering a much faster training speed than High Detail along with all the merits of High Detail mode. Users can switch between modes without relabeling the images. This makes it easy to determine which mode offers the best combination of accuracy & speed for any particular application.

- VisionPro Deep Learning is compatible with VisionPro ViDi, including API, project loading and security dongles.

- SuaKIT users can import SuaKIT classification and segmentation project into VisionPro Deep Learning. They can then take advantage of the other features of Cognex Deep Learning Studio, including the Blue Locate, OCR tools, and tool chaining.
