Nettet17. jun. 2024 · I have a segmentation model in onnx format and use trtexec to convert int8 and fp16 model. However, trtexec output shows almost no difference in terms of execution time between int8 and fp16 on RTX2080. I expect int8 should run almost 2x faster than fp16. I use the following commands to convert my onnx to fp16 and int8 trt engine. Nettet30. jun. 2024 · 7. No. int8 is an alias for bigint. You can check for yourself - CREATE TABLE foo (bar int8);, then \d foo in psql. You'll see that column bar has type bigint. – AdamKG.
