1610	Frame lost when the default NNPF config files are applied in coding.	shurunwang		"VTM version is VTM-21.2, and the encoding configuration is random access (RA) with the given random access config file.
Using the default NNPF config files to compress video, frames could be lost in the decoded YUV file in the decoding process, while no frame lost in the reconstructed YUV file in encoding process. 
Here are the sequence names and the related settings when frames are lost. (QP is 63 to save coding time.)
