GPU->CPU Memcpy failed

[talmazov]

Hey everyone, I am trying to run a training on 2 CBCT segmented volumes but I am running into an issue of GPU->CPU Memcpy failed. I was reading around in the tensorflow repo that it is an issue of insufficient memory so i reduced the size of the volumes drastically, as well as the batch_size and queue_length however I still get this error. I have included the configuration file here. My PC runs on 32 GB of RAM and GeForce RTX2060 w/ 6GB VRAM. NiftyNet and TensorFlow recognize the device. I have CUDA 10 installed on the nvidia driver 418 w/ cuDNN 7.6.3 When i run in the python console sess = tf.Session(config=tf.ConfigProto(log_device_placement=True)) the GPU appears and everything is fine

Most notably I see "could not create cudnn handle: CUDNN_STATUS_INTERNAL_ERROR" then when niftynet performs a Parameters from random initialisations where the shuffle buffer is filled, it gives the GPU->CPU memcpy failed error 2019-08-24 17:21:52.622248: I tensorflow/core/kernels/data/shuffle_dataset_op.cc:162] Shuffle buffer filled.

I do not get this issue when performing training on the CPU.

I switched the networks from dense_vnet to highres3dnet and at this point I only get the "Could not create cudnn handle" error. I modified the util_common.py tf_config() method to include config.gpu_options.allow_growth = True as described in https://github.com/tensorflow/tensorflow/issues/24496 but that does not seem to address the issue.

Any thoughts? Is this an issue of not enough VRAM?

the command i use to run is python3 net_segment.py train -c ~/mandible_segmentation/config.ini

My configuration is

running the following code from within python3 cli works just fine

with tf.device('/gpu:0'):
    a = tf.constant([1.0, 2.0, 3.0, 4.0, 5.0, 6.0], shape=[2, 3], name='a')
    b = tf.constant([1.0, 2.0, 3.0, 4.0, 5.0, 6.0], shape=[3, 2], name='b')
    c = tf.matmul(a, b)

with tf.Session() as sess:
    print (sess.run(c))

Did you find any solution for this issue?

Did you find any solution for this issue?

no solution. I suspect this is an issue with the underlying code not being able to copy data between system RAM and VRAM but im not sure why - i see the bug was assigned to someone. for now either drastically decrease the DICOM resolution or increase you graphics card's available VRAM. Also to be fair, processing CT/CBCT DICOM even on CPU (which does not produce this error), my PC maxes out 32gigs of RAM easily

Just Change the Tensorflow version! It dose work !

Hey, so i tried again, when i run tensorflow GPU for object detection everything runs fine. I have installed numpy 1.16.0 amd tensorflow-gpu 1.13.2 however i still get the GPU-CPU memcpy failed

i am not sure why CUDNN handle could not be created

what version of cuDNN is everybody else running?? i have niftynet 0.6, CUDA 10.0, tensorflow-gpu 1.13.2 and numpy 1.16 using geforce RTX 2060 6GB vram with nvidia driver 440.33.01 tensorflow tries to allocate 5 GB spatial_window_size = (64, 64, 512) with dense_vnet network

is this a common error thrown when the GPU does not have enough physical memory to run training?
