CuDNNLSTM: UnknownError: Fail to find the dnn implementation

I have run the model with LSTM as the first layer successfully. But out of curiosity, I replace LSTM with CuDNNLSTM. But after model.fit, it replied the following error message:

UnknownError: Fail to find the dnn implementation.
    [[{{node cu_dnnlstm_5/CudnnRNN}} = CudnnRNN[T=DT_FLOAT, _class=["loc:@training_2/Adam/gradients/cu_dnnlstm_5/CudnnRNN_grad/CudnnRNNBackprop"], direction="unidirectional", dropout=0, input_mode="linear_input", is_training=true, rnn_mode="lstm", seed=87654321, seed2=0, _device="/job:localhost/replica:0/task:0/device:GPU:0"](cu_dnnlstm_5/transpose, cu_dnnlstm_5/ExpandDims_1, cu_dnnlstm_5/ExpandDims_1, cu_dnnlstm_5/concat_1)]]
    [[{{node metrics_3/mean_squared_error/Mean_1/_1877}} = _Recv[client_terminated=false, recv_device="/job:localhost/replica:0/task:0/device:CPU:0", send_device="/job:localhost/replica:0/task:0/device:GPU:0", send_device_incarnation=1, tensor_name="edge_4852_metrics_3/mean_squared_error/Mean_1", tensor_type=DT_FLOAT, _device="/job:localhost/replica:0/task:0/device:CPU:0"]()]]

I have tried TestCudnnLSTM() on this discussion and pass the test successfully:

Keras version: 2.2.4
Tensorflow version: 1.12.0

It seems that the problem appears during model fitting. But I don't know exactly what is the problem?

For me, the issue was resolved after installing the correct version of Tensorflow for the installed CUDA version. The correct matches can be seen from here: https://www.tensorflow.org/install/source#gpu. To check CUDA version installed on machine, use nvcc --version.

My code worked after I check all the versions of the following packages: cuda, cudnn, tensorflow and gcc. You need to find the corresponding version for all, hope it helps!

Mine version is below:

  • Cuda 11.1
  • Gcc-9
  • Cudnn-8.2
  • Tensorflow-2.6
  • keras-2.6
  • python-3.6

Also check that the cuDNN is present for the CUDA version your application uses.

Upgrading tensorflow can cause it using another CUDA version

For instance tensorflow-2.3 uses CUDA 10.1 but tensorflow-2.5 uses 11.2

I got the same error in Windows and I had to copy the latest cuDNN DLL's into the "c:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.2" folder

I would recommend checking if any other kernel has imported tensorflow or keras. If yes, shutdown that kernel - even if it is not busy. It solved the problem in my case.

I Installed tensorflow and keras using conda in the Virtual env and this solved it.

conda install tensorflow
conda install keras

For TensorFlow v2, one solution would be -

import tensorflow as tf
physical_devices = tf.config.list_physical_devices('GPU')
tf.config.experimental.set_memory_growth(physical_devices[0], enable=True)

Then you can use keras model too -

from tensorflow.keras.models import Model

Documentation

This solution worked for me, it enables memory growth for only one GPU.

In tensorflow 2.0 i got the same error while running RNN LSTM model.The reason was due to lower version of my cuDNN.In the tensorflow gpu requirements page it was recommended to have

cuDNN SDK >= 7.4.1.

You can refer for more details in https://www.tensorflow.org/install/gpu

Asked in Tensorflow Reddit forum

If you're getting this error while fitting Keras NN put this code on your import

from keras.backend.tensorflow_backend import set_session
import tensorflow as tf
config = tf.ConfigProto()
config.gpu_options.allow_growth = True
sess = tf.Session(config=config)
set_session(sess)

I had the same issue , when I updated tensorflow to 1.12. Error got resolved after updating my CuDNN verstion to 7.5 from 7. I followed the steps mentioned in the below url for updating the CuDNN version (Note: The steps mentioned in the link are for installing CUDNN , but the same is applicable for update as well)

Make sure you have the proper Nvidia driver version for the version of CUDA you are using. You can check it out here. https://docs.nvidia.com/deploy/cuda-compatibility/index.html#binary-compatibility

I'm using CUDA 9.0, but was using Nvidia driver less than 384.81. Updating the Nvidia driver to a newer one fixed the problem for me.
