what those "errors" when running Adobe DNG Converter in command line mode ( v16.0.0.1677 on Windows 10x64 ) might be ?

*** Error: Exception in GetRuntimeModelZooPaths (). ***
*** GPU Warning: GPU3 disabled via cr_config at init time. ***
*** Error: ComputeRawDepthModelKey () model #1 not present ***
*** Error: ComputeRawDepthModelKey () model #2 not present ***
*** Error: ComputeBaseLayeredDepthModelKey () - mask-guided refinement model not present ***
*** Error: ComputeBaseFocalMatteModelKey () model not present ***

DNG file still created, but why the messages ?

they are silently written to logs in C:\Users\Administrator\AppData\Roaming\Adobe\CameraRaw\Logs ( user = Administrator in this case )  creating 2 files

DNG Converter Log Latest v0.txt
DNG Converter Log Latest v1.txt

when I use dng converter just in a command line in Windows 

however when I run the command line from within Matlab it pollutes the system ( Matlab function : [status,cmdout] = system(command) )  output to "cmdout"
