I tested training the same deepfake model on the same hardware using tensorflow-cuda and tensorflow-directml. (my project https://github.com/iperov/DeepFaceLab)

DirectML: avg iter time 626ms

CUDA: avg iter time 222ms

DirectML is x2.8 slower :-(

I think that's what I was talking about here https://github.com/microsoft/DirectML/issues/104

So what is the point of using DirectML if every millisecond of training acceleration is important in today's world?

x2.8 slower is serious performance degradation. I reached the same speed in my weekend OpenCL NN library in pure python (https://github.com/iperov/litenn)

But you are guys from microsoft company. Don't you think there is no point in further development of DirectML until you reach the level of CUDA performance?

Followed the instructions here

Hi,

After following the steps described in https://docs.microsoft.com/en-us/windows/win32/direct3d12/gpu-tensorflow-wsl till pip install tensorflow-directml,

the error appeared as

ERROR: Could not find a version that satisfies the requirement tensorflow-directml (from versions: none) ERROR: No matching distribution found for tensorflow-directml

BTW, I am using python 3.8

and I did python list tensorflow*, which outputed

Hi, For accessing available devices in Pytorch we'd normally do :

    print(f'available devices: {torch.cuda.device_count()}')
    print(f'current device: { torch.cuda.current_device()}')

However, I noticed this fails (AssertionError: Torch not compiled with CUDA enabled).
I thought the transition would be minimal, and stuff like this would work out of the box! especially so, after noting we cant write:

    print(f'available devices: {torch.dml.device_count()}')
    print(f'current device: { torch.dml.current_device()}')

as it fails with the error :

AttributeError: module 'torch.dml' has no attribute 'device_count'

Apart from this, trying to specify a device using the form "dml:number" fails if number>1! that is this fails for "dml:1":

import torch 
import time
def bench(device ='cpu'):
    print(f'running on {device}:')
    a = torch.randn(size=(2000,2000)).to(device=device)
    b = torch.randn(size=(2000,2000)).to(device=device)
   
    start = time.time()
    c = a+b
    end = time.time()
    
    # print(f'available devices: {torch.dml.device_count()}')
    # print(f'current device: { torch.dml.current_device()}')
    print(f'--took {end-start:.2f} seconds')

bench('cpu')
bench('dml')
bench('dml:0')
bench('dml:1')    

it outputs :

running on cpu:
--took 0.00 seconds
running on dml:
--took 0.01 seconds
running on dml:0:
--took 0.00 seconds
running on dml:1:

and thats it, it doesnt execute when it comes to "dml:1".

also trying to do :

import torch 
import time
def bench(device ='cpu'):
    print(f'running on {device}:')
    a = torch.randn(size=(2000,2000)).to(device=device)
    b = torch.randn_like(a).to(device=device)
    
    start = time.time()
    c = a+b
    end = time.time()
    
    # print(f'available devices: {torch.dml.device_count()}')
    # print(f'current device: { torch.dml.current_device()}')
    print(f'--took {end-start:.2f} seconds')

bench('cpu')
bench('dml')
bench('dml:0')
bench('dml:1')    

Fails with the following error :

I ran across directML a few hours ago and am currently playing around with it on a Surface Pro 6 with an Intel HD Graphics 620. To set it all up, I followed this article to the letter: https://docs.microsoft.com/en-us/windows/win32/direct3d12/gpu-tensorflow-windows

For testing purposes, I used a slightly modified version of my small go-to script:

import tensorflow.compat.v1 as tf 

tf.enable_eager_execution(tf.ConfigProto(log_device_placement=False)) 

fashion_mnist = tf.keras.datasets.fashion_mnist
(train_images, train_labels), (test_images, test_labels) = fashion_mnist.load_data()


class_names = ['T-shirt/top', 'Trouser', 'Pullover', 'Dress', 'Coat',
               'Sandal', 'Shirt', 'Sneaker', 'Bag', 'Ankle boot']

train_images = train_images.reshape(60000, 28, 28, 1)
train_images = train_images / 255.0

test_images = test_images.reshape(10000, 28, 28, 1)
test_images = test_images / 255.0

#model = tf.keras.Sequential([
#    tf.keras.layers.Flatten(input_shape=(28, 28, 1)),
#    tf.keras.layers.Dense(128, activation=tf.nn.relu),
#    tf.keras.layers.Dense(10, activation=tf.nn.softmax)
#])

model = tf.keras.Sequential([
    tf.keras.layers.Conv2D(64, (3,3), activation=tf.nn.relu, input_shape=(28, 28, 1)),
    tf.keras.layers.MaxPooling2D(2,2),
    tf.keras.layers.Flatten(),
    tf.keras.layers.Dense(128, activation=tf.nn.relu),
    tf.keras.layers.Dense(10, activation=tf.nn.softmax)
])

model.compile(optimizer='adam',
              loss='sparse_categorical_crossentropy',
              metrics=['accuracy'])

model.fit(train_images, train_labels, epochs=5)

test_loss, test_acc = model.evaluate(test_images,  test_labels, verbose=2)

print('Test accuracy:', test_acc)

The version of the model without convolutions runs absolutely fine. But as soon as I add the Conv2D layer, nothing works anymore.

The entire output I get is:

Any ideas?

Hi,

I've recently purchased a 6900 xt GPU which I would like to use with tensorflow. I followed the installation guide on https://docs.microsoft.com/en-us/windows/win32/direct3d12/gpu-tensorflow-windows which worked but the issue I have now is that whenever I try to use tensorflow it closes my python environment.

I've attached an image to show what I mean. I can import tensorflow fine and it shows me that I have version 1.15.5 available. The problem is when I want to check if my GPU is available I get two messages and then it crashes me out of my python environment.

Does anybody know how to solve this issue and what is going on?

Thank you in advance!

Hello,

I'm experiencing a runtime crash with the C++ DirectML API in Debug x64 mode after upgrading my NuGet package Microsoft.AI.MachineLearning from version 1.4.0 to 1.5.2. There is no error in Release x64 mode.

The reason why I'm using this package is because the included DirectML.dll improves DirectML performance greatly. There seems to be an issue when creating a DirectMLOperator. The operator type is DML_OPERATOR_JOIN.

Can you please help me identify the issue? Also how can I find the latest DirectML.dll file without downloading the package?

I am investigating for the performance of MobileNet V2 from TFLite models with "nhwc" layout and MobileNet V2 from ONNX models with "nchw" layout on the implementation with DirectML and DirectMLX API.

I find that nhwc MobileNetV2 model has lots of Clip after Conv2d, the Clip will cost much time on inference. I guess that the Clip will do memory copy and hasn't be optimized in compilation stage.

I have a workaround to resolve this problem: set Clip's input strides same as its' output strides by changing this lineto TensorDesc outputTensor = inputTensor in DirectMLX.h, the Clip will be optimized just like fused into Conv2d, and then the inference time will be significantly reduced to be as same as nchw MobileNetV2.

When building nhwc MobileNetV2 model, we need append Identity after each Conv2d to transpose output tensor from default nchw to nhwc, then transpose this output tensor from nhwc to nchw as the next Conv2d's input tensor. In my opinion, I suppose that the Identity and Reinterpret can be optimized by DML in this model like: Conv0->Identity(nchw->nhwc)->Reinterpret strides(nhwc->nchw)->Conv1 just like transpose sinking in OpenVINO backend.

I guess that the Identity and Reinterpret sinking may be blocked when there is Clip like: Conv0->Identity(nchw->nhwc)->Clip->Reinterpret strides(nhwc->nchw)->Conv1 . I verified that if I remove Identity to run Conv0->Reinterpret strides(nchw->nhwc)->Clip(input strides = output strides)->Reinterpret strides(nhwc->nchw)->Conv1, the inference time will be much lower than before.

So in conclusion, I suggest setting Clip's input strides same as its' output strides by changing this line to TensorDesc outputTensor = inputTensor in DirectMLX.h.

The current DirectML library for GPU is more 2x slower than the TensorFlow CPU library. When DirectML team will improve the performance of the library? Could you share a roadmap of DirectML? Will DirectML team cooperate with ROCm team (https://github.com/RadeonOpenCompute/ROCm), Intel and Nvidia for improving performance?

just trying simple command with pytorch-directml 1.8.0a0.dev220224 and getting error

hi, now I have a quick enough model (120fps) and will run at 20fps, what i need is use as low as possible gpu power. but i find the gpu frequency jump to 1150mhz too many times. as compare to "https://voovmeeting.com/download-center.html?from=1001" tencent meeting , I found when I enable human segmentation , in a 8xxx laptop, the gpu frequency hold below 400mhz , but GPU load over 75%, that is strange for frequency policy.
so I guess , maybe directx12 or dx11 has some low power mode ? or some other ways, for ex. add some wait in each OP (for ex. convolution op）

I was trying to run the simple code below:

import torch import torch_directml dml = torch_directml.device()

print(f"dml={dml}")

tensor1 = torch.tensor([1]) print(tensor1) tensor1=tensor1.to(dml)

when runing tensor1.to(dml), i got the following error: [W dml_heap_allocator.cc:97] DML allocator out of memory! Traceback (most recent call last): File "/home/fnz/workspace/direct-ml/main.py", line 9, in tensor1=tensor1.to(dml) RuntimeError: Unknown error -2147024882

It seems that my pytorch-directml doesn't work at all.

below is my package in conda: (direct_ml) [email protected]:~/workspace/direct-ml$ conda list | grep torch torch 1.13.1 pypi_0 pypi torch-directml 0.1.13.dev221216 pypi_0 pypi

BTW, my environment is wsl2 on top of windows 11 pro .

The tensorflow directml seems working well.

any idea ?

thanks

Hi, Because 'aten::fmod.Tensor_out' is not implemented, I tried to implement it myself. I encountered a new error when using the rounding mode trunc with a int64 tensor.

Code:

import torch
import torch_directml
dml = torch_directml.device()

a = torch.tensor([1,2,3]).to(dml) #
b = 2
a = a - torch.div(a, b, rounding_mode="trunc") * b

Hello everyone. I am facing an issue. I am explaining what I am trying to do. I have a Traffic and Road sign dataset that contains 43 classes. I am trying to classify the images. I am using the resnet34 pre-trained model. I have AMD RX6600 GPU that I use for running the model. For running the model on my AMD GPU I am using Pytorch Directml. Until now everything has worked fine. Training speed is fast enough, and GPU utilization is near 100%. Training loss decreases per epoch. But when I check the model using validation data after one training phase, validation loss increases and validation accuracy is too low. But training is ok. When I run the same code on my friend’s PC who has NVIDIA GPU, all is ok. Validation loss decreases and it converges. And I got an accuracy of 98% when running the same code on NVIDIA GPU. I can not figure out what the problem is. I also tune the hyperparameter but had no luck. And one strange thing is that this problem arises when I use CNN based model. I had run NLP pre-trained model BERT on my AMD GPU and there is no Issue. Validation loss decreases and it converges. Can anyone help me with this issue? I am giving the code below. Thanks in advance.
