tensorRT error: UffParser: Graph error: cycle graph detected

Hello, I met this error:

[TensorRT] ERROR: UFFParser: Graph error : Cycle graph detected
AttributeError:Enter

I download the ssd_mobilenetv1 from the website and use the command:
convert-to-uff
to change the .pb to .uff.
When I want to change .uff to .engine, it would appear these errors.
Can anyone help me solve this problem?
Thanks!

Hi,

Please try again with the latest version of TensorRT. There is an example here: https://docs.nvidia.com/deeplearning/sdk/tensorrt-sample-support-guide/index.html#uffssd_sample
