Program using cuda does not work on ec2

[Hiroaki-K4]

Hi, I got below error when I run the program on EC2(g5xlarge). The command is below.

./bin/stitcherSDKDemo -inputs ${TARGET_INPUT_INSV_00_FILE} ${TARGET_INPUT_INSV_10_FILE} -output ${OUTPUT_MP4_FILE} -stitch_type optflow -bitrate 30000000 -output_size 5760x2880

The environment is below.

• EC2(g5xlarge)
• AMI(Deep Learning AMI GPU PyTorch 1.12.1 (Ubuntu 20.04) 20221114)
• cuda10.2(docker)

The error message is below.

pls update sdk version and try, but we cannot ensure NVIDIA A10G is supported

[Hiroaki-K4]

It seems that the target GPU is not supported because I could not get it to work even after upgrading the version.
