当我将误差较大的层送入TargetPlatform.FP32后，生成int8.onnx，但是无法生成对应的int8.engine文件，报错如下：

Traceback (most recent call last):
File "/work_dir/demo/ppq_code/int8trt.py", line 2, in
build_engine(onnx_file='/work_dir/demo/models/6-x-slimneck-best(PPQ_2).onnx',
File "/usr/local/lib/python3.10/dist-packages/ppq-0.6.6-py3.10.egg/ppq/utils/TensorRTUtil.py", line 263, in build_engine
f.write(engine.serialize())
AttributeError: 'NoneType' object has no attribute 'serialize'

请问怎么解决这个问题呢？

我也遇到了，是这个build_engine(onnx_file='/work_dir/demo/models/6-x-slimneck-best(PPQ_2).onnx返回值是None，所以报了一个这个错误
