I've got the same error with Google Colab.

When I run

with trt.Builder(TRT_LOGGER) as builder, builder.create_network(*EXPLICIT_BATCH) as network, trt.OnnxParser(network, TRT_LOGGER) as parser:
  builder.max_workspace_size = 1 << 28
  builder.max_batch_size = 1
  builder.fp16_mode = True

I've got

Hi @DineshRajanT ,

Please provide a minimal but complete script to reproduce the issue, not just the snippet.
