Hello,
I am using Jetson TX2 with JetPack 3.3, Tensorflow 1.11.0, libnvinfer 4.1.3, Cuda 9.0.
I am trying to create_inference_graph using my saved keras model using the trt.create_inference_graph function according to this tutorial: [url]https://docs.nvidia.com/deeplearning/frameworks/tf-trt-user-guide/index.html#using-savedmodel[/url]
I have imported trt as:
import tensorflow.contrib.tensorrt as trt
As per most of the imports, “from tensorflow.python.compiler.tensorrt import trt_convert” is not available and hence I use “import tensorflow.contrib.tensorrt as trt”
However, I get an error saying: “TypeError: create_inference_graph() got an unexpected keyword argument ‘input_saved_model_dir’”
When I check the trt_convert.py located at":/usr/local/lib/python3.5/dist-packages/tensorflow/contrib/tensorrt/python/, the function definition itself does not take the “input_saved_model_dir”, “input_saved_model_tags” parameters as input: The function from the trt_convert.py is as below:
def create_inference_graph(input_graph_def,
outputs,
max_batch_size=1,
max_workspace_size_bytes=2 << 20,
precision_mode=“FP32”,
minimum_segment_size=3,
is_dynamic_op=False,
maximum_cached_engines=1,
cached_engine_batches=None):
This definition is different the one found here: [url]https://github.com/tensorflow/tensorflow/blob/master/tensorflow/python/compiler/tensorrt/trt_convert.py[/url]
I am not sure what I am missing here. Is it that the version of tensorrt is not updated?
Appreciate some help!
Hi,
The API has changed from TensorRT 5.0.
I’m not sure if it is compatible to the TensorFlow package you used.
Is any special reason to use JetPack3.3?
We have a newer JetPack4.2 to support Jetson TX2.
It’s recommended to give it a try.
Thanks.
I tried installing the newer JetPack 4.2 but the installations were not going through the GUI. I figured the .run installer was much easier (Although it had its own issues, but still I could move ahead with it.)
From what you are saying I might have to flash a new jetpack version. Do I have to uninstall the older version in some way? Is there a .run installer available for JetPack 4.2 too?
So I tried my luck again with JetPack 4.2. This time I achieved better success than the last time, however there are still some issues:

However target installation and flashing completes successfully.
2. When I see the target screen, I cannot find any installed files and folders. Like tegra_multimedia_api, visionworks samples, etc,. which I found when I installed jetpack 3.3 successfully.
I am not sure where I am going wrong. Really appreciate your help!
Thank you!
Hi,
It looks like there is some issue in installing the package on the host.
This is related to GPU card, GPU driver, CUDA, Ubuntu version, … on the host, which is pretty complicated.
To get JetPack4.2, you can just uncheck the host item and try it again.
Thanks.
Hello AastaLL,
JetPack 4.2 worked well. I had issues with CUDA Compiler on host, but target flashed successfully. I was not able to find the tegra_multimedia_api and other CUDA samples in the Home directory (JetPack 3.3 installed these in the Home directory, so when I didn’t see the particular folders mentioned above in the Home directory I thought something might have gone wrong). But later found them here: /usr/src/
Thank you!
