If memory growth is enabled for a PhysicalDevice, the runtime initialization will not allocate all memory on the device. Memory growth cannot be configured on a PhysicalDevice with virtual devices configured.
For example:
import tensorflow as tf
physical_devices = tf.config.list_physical_devices('GPU')
try:
tf.config.experimental.set_memory_growth(physical_devices[0], True)
except:
# Invalid device or cannot modify virtual devices once initialized.
pass

How to initialize a kernel with a tensor

I have created a custom layer in keras, which simply perform a dot product between the input and a kernel. But for the kernel I wanted to use the mean of the batch as a kernel initialization, meaning taking the mean of the batch and producing a kernel which initial value is that mean. To do so I have created a custom kernel initializer as follow:
class Tensor_Init(Initializer):
"""Initializer that generates tensors initialized to a given tensor.
# Arguments
Tensor: the generator tensors.
"""
def __init__(self, Tensor=None):
self.Tensor = Tensor
def __call__(self, shape, dtype=None):
return tf.Variable(self.Tensor)
def get_config(self):
return {'Tensor': self.Tensor}
This is the call method of the custom layer in keras. I simply compute the mean of the batch and use it with the above initializer class to produce a kernel. I use it as follow in the custom layer
def call(self, inputs):
data_format = conv_utils.convert_data_format(self.data_format, self.rank + 2)
inputs = tf.extract_image_patches(
inputs,
ksizes=(1,) + self.kernel_size + (1,),
strides=(1,) + self.strides + (1,),
rates=(1,) + self.dilation_rate + (1,),
padding=self.padding.upper(),
)
inputs = K.reshape(inputs,[-1,inputs.get_shape().as_list()[1],inputs.get_shape().as_list()
[2],self.kernel_size[0]*self.kernel_size[1] ,self.output_dim])
self.kernel = self.add_weight(name='kernel',shape=(),initializer=Tensor_Init(Tensor=tf.reduce_mean(inputs, 0)),trainable=True)
outputs = (tf.einsum('NHWKC,HWKC->NHWC',inputs,self.kernel)+self.c)**self.p
if self.data_format == 'channels_first':
outputs = K.permute_dimensions(outputs, (0, 3, 1, 2))
return outputs

Error using tensorflow graph transform tool

I am trying to use the graph transform tool on a tensorflow object detection model for tensorflow 1.4.1 in Linux Ubuntu 16.04

When I try to query the optimized tensorflow graph,

I do not know what is wrong, as the original frozen graph works fine.

Problem solved. Its a version issue. The model was generated in a different version than the GTT.

How can i save tensors object to an numpy array?

I have implemented autoencoder on my custom images data for sign language recognition.Now i want to save tensors object of the output layer to an numpy array. I tried Session.run(tensor) and tensor.eval(). Here is my code.
#define model
x= tf.placeholder(tf.float32,[None,784])
y_=tf.placeholder(tf.float32,[None,6])
k=190
l=180
m=150
n=130
o=100
num_of_epoch=10
w1=tf.Variable(tf.truncated_normal([784,k],stddev=0.1))
b1=tf.Variable(tf.zeros([k]))
w2=tf.Variable(tf.truncated_normal([k,l],stddev=0.1))
b2=tf.Variable(tf.zeros([l]))
w3=tf.Variable(tf.truncated_normal([l,m],stddev=0.1))
b3=tf.Variable(tf.zeros([m]))
w4=tf.Variable(tf.truncated_normal([m,n],stddev=0.1))
b4=tf.Variable(tf.zeros([n]))
w5=tf.Variable(tf.truncated_normal([n,o],stddev=0.1))
b5=tf.Variable(tf.zeros([o]))
w6=tf.Variable(tf.truncated_normal([o,6],stddev=0.1))
b6=tf.Variable(tf.zeros([6]))
y1=tf.nn.relu(tf.matmul(x,w1)+b1)
y2=tf.nn.relu(tf.matmul(y1,w2)+b2)
y3=tf.nn.relu(tf.matmul(y2,w3)+b3)
y4=tf.nn.relu(tf.matmul(y3,w4)+b4)
y5=tf.nn.relu(tf.matmul(y4,w5)+b5)
y=tf.nn.softmax(tf.matmul(y5,w6)+b6)
cross_entropy=tf.reduce_mean(-tf.reduce_sum(y_*tf.log(y),
reduction_indices=[1]))
train_step=tf.train.GradientDescentOptimizer(0.03).minimize(cross_entropy)
init=tf.global_variables_initializer()
with tf.Session() as sess:
sess.run(init)
for i in range(num_of_epoch):
train_data = {x:x_train,y_:y_train}
sess.run(train_step,feed_dict=train_data)
currect_prediction=tf.equal(tf.argmax(y,1),tf.argmax(y_,1))
accuracy=tf.reduce_mean(tf.cast(currect_prediction,tf.float32))
sess.run(accuracy,feed_dict={x:x_train,y_:y_train})
currect_prediction=tf.equal(tf.argmax(y,1),tf.argmax(y_,1))
accuracy=tf.reduce_mean(tf.cast(currect_prediction,tf.float32))
sess.run(accuracy,feed_dict= {x:x_test,y_:y_test})
y_p = tf.argmax(y, 1).eval() #this line shows me the error
print(y_p)
I am getting the below error. How can I fix this error and save tensor data to numpy array ?

That's because y is a tensor in the graph and not a variable. When you run .eval() on a variable, it gives you the current value held by that variable in that session but if you run .eval() on a tensor instead like tf.argmax(y, 1).eval() in your case then tensor flow runs the graph to that node to get the value of that node. And since in your case, it doesn't get the value of the placeholder x and y_ while running the graph, it gives the error. One way to resolve this error is by passing the values of the placeholders in your eval call like this:
tf.argmax(y, 1).eval(feed_dict= {x:x_test,y_:y_test})
But, a more preferred way is giving the context of your session to the eval call in which case it will return the value of the tensor. Ex:
tf.argmax(y, 1).eval(session = sess)

Your question is not 100% clear. But the error you are seeing is caused by the fact that you try to run the graph without the feed dict in place. To see the output of the prediction (that is with the argmax(y, 1) present) you'd simply run:
y_p = sess.run(tf.argmax(y, 1), feed_dict=train_data)
print(y_p)
But that will give you the actual predicted value (on the train data as this is fed, to get this on the test data, simply geed in the test_data). To get the probabilities you'd pull y without the argmax:
y_p = sess.run(y, feed_dict=train_data)
print(y_p)

Argument error with feed_dict

I got confused about feed_dict. I can feed my datasets as X but I cannot feed Y labels. all dtype are tf.float64 and I printed it out, and yes, they are float64. My X dataset has shape 90,32,32,3 and my Y is 90,2. so I defined a plaeholder to be fed with the same shape.
but when I run my code, error comes out :
InvalidArgumentError: You must feed a value for placeholder tensor 'Placeholder_34' with dtype double
[[Node: Placeholder_34 = Placeholder[dtype=DT_DOUBLE, shape=[], _device="/job:localhost/replica:0/task:0/cpu:0"]()]]
I have no idea why this happened, since I am really sure that both X and Y are float64. X is fine but why only Y? Please help, I really appreciate :)
here's the code :
size_image =32
allX = np.zeros((100, size_image, size_image, 3), dtype='float64')
ally = np.zeros(100, dtype='float64')
count = 0
for i in range(49):
img = io.imread("cat/cat"+str(i+1)+".jpg")
new_img = imresize(img, (size_image, size_image, 3))
allX[count] = np.array(new_img)
ally[count] = 0
count += 1
#dog images and labels
for i in range(51):
img = io.imread("dog/dog"+str(i+1)+".jpg")
new_img = imresize(img, (size_image, size_image, 3))
allX[count] = np.array(new_img)
ally[count] = 1
count += 1
#splitting dataset supaya random
X, X_test, Y, Y_test = train_test_split(allX, ally, test_size=0.1, random_state=42)
# encode the Ys
Y = to_categorical(Y, 2)
Y_test = to_categorical(Y_test, 2)
x = tf.placeholder(tf.float64, [None,None, None,3])
y_ = tf.placeholder(tf.float64, [None, 2])
sess = tf.Session()
sess.run(init)
t = x*2
print(sess.run(t, feed_dict={x:X}))
m = 1*y
print(sess.run(m, feed_dict={y_:Y}))
and here is the traceback :
