# Resolved Issues

This section describes changes and resolved issues in VisionPro Deep Learning 2.1.

- Fixed an issue that some runtime API example codes were unable to be run because of missing DLL files.

- Fixed an issue in High Detail Mode tools that the training time keeps increasing when training multiple High Detail mode tools in sequence.

- Fixed an issue in Parameter Search that searching parameters for a Red Analyze tool already trained in VisionPro Deep Learning unnecessarily copies existing .vvb files and thus grows the size of the current workspace.

- Fixed an issue in C API that 32-bit images (8-bit, 4 channel) added to a workspace by C API look bizarre when they are viewed in GUI.

- Fixed an issue in Loss Graph that the Elapsed Time in Status table is not in accordance with the elapsed time in Progress bar.

- Fixed an issue in Loss Graph that the Elapsed Epoch in Status table and Epoch in the loss graph are displayed incorrectly.

- Fixed an issue that the value of ViDi2.View.maskCache keeps increasing and consumes memory.

- For High Detail modes, fixed an issue that processing with GPU designation is not available when calling ISample.Process().

- For VisionPro Deep Learning Client/Server environment, fixed an issue that VisionPro Deep Learning Client/Server cannot accept "16-bit depth, png/tiff format" image file as its input image.

- For runtime workspaces, fixed an issue that users cannot get the label information of Green Classify High Detail with Runtime.IGreenTool.KnownTags

- For Red Analyze, fixed an issue that after changing mode of tool operation (Supervised, Unsupervised) the class of a region is displayed incorrectly.

- For Red Analyze, fixed an issue that after changing mode of tool operation (Supervised, Unsupervised) a region cannot be modified with Edit Region.

- For Red Analyze High Detail, fixed an issue that if you change the mode of a Red Analyze tool to Red Analyze High Detail, add images, set ROI, and train with the default tool parameters, the score for a view is not generated.
