Cudnn not Initializing

Hi there,

I am currently trying to run a Neural Network using TensorFlow:

import tensorflow as tf
import numpy as np

tf_config = tf.ConfigProto()
tf_config.gpu_options.allow_growth = True
tf_sess = tf.Session(config=tf_config)
tf.import_graph_def(trt_graph, name='')

output_tensor_name = 'reshape_5/Reshape' + ":0"
output_tensor = tf_sess.graph.get_tensor_by_name(output_tensor_name)

print("input_tensor_name: {}\noutput_tensor_name: {}".format(
    input_tensor_name, output_tensor_name))

output_tensor = tf_sess.graph.get_tensor_by_name(output_tensor_name)  

feed_dict = {
    input_tensor_name: [np.load("testdata.npy")]
}
preds = tf_sess.run(output_tensor, feed_dict)

However I am getting the following error message on the last line:

---------------------------------------------------------------------------

Hi,

May I know how do you setup your environment?

Please noticed that there are several dependencies between CUDA, cuDNN and TensorRT.
You will need to install the package which is built on the same JetPack environment as yours.

Thanks.

I am using the r32.1 sd card image. To install TensorFlow I followed the instructions shown here: Installing TensorFlow for Jetson Platform :: NVIDIA Deep Learning Frameworks Documentation.

My neural network was initially built and trained on pc using keras (with tensorflow 1.14 underlying). I then froze the graph and converted to a .pb format. I then ran tensorRT on it before transferring the optimised .pb file over to the Nano.

I noticed you have released a new version (r32.2) so I will give that one a try and see if I get the same issues.

Hi,

Your installation steps looks correct to me.

Would you mind to verify if cuDNN is working on your environment first.

$ cd /usr/src/cudnn_samples_v7/mnistCUDNN/
$ sudo make
$ ./mnistCUDNN

Thanks.

Exact same problem and setup approach. Trained and optimized with TRT in tf-1.14. Ran the mnistCUDNN and it returned Test Passed!

Hey worked out how to fix this. A lot of tutorials online run the tensorRT the way I did above but this did not work for me. However, this did (replacing lines 16 onwards from my own code):

with tf.Graph().as_default() as graph:
    tf_config = tf.ConfigProto()
    tf_config.gpu_options.allow_growth = True
    tf_sess = tf.Session(config=tf_config)

    tf.import_graph_def(comp_graph, name="")

    output_tensor = tf_sess.graph.get_tensor_by_name(output_tensor_name)

    feed_dict = {
        input_tensor_name: inputs
    }

    with tf.Session(graph=graph) as sess:
        y_out = sess.run(output_tensor, feed_dict)
