My deepstream 5 test 1 .py have lot of ERROR / WARN

i test on my h264 1280x720 movie and after up and running have this messages:

–> Deserialize engine failed…resnet10.caffemodel_b1_gpu0_int8.engine open error

–> WARNING: INT8 not supported by platform. Trying FP16 mode.

–> ERROR: [TRT]: Network has dynamic or shape inputs, but no optimization profile has been defined.

and many others
