Python – tensorflow.IndexedSlices.op Attribute

TensorFlow is open-source Python library designed by Google to develop Machine Learning models and deep learning  neural networks.

op is used to find the operation used to that produces value as an output. It only works when eager execution is disabled.

Syntax: tensorflow.IndexedSlices.op

Returns: It returns the operation that produces values as an output.

Example 1: In this example eager execution is disabled.

Python3

# Importing the library
import tensorflow as tf

# Disable Eager execution
tf.compat.v1.disable_eager_execution()

# Initializing the input
data = tf.constant([[1, 2, 3], [4, 5, 6]])

# Printing the input
print('data: ', data)

# Calculating result
res = tf.IndexedSlices(data, [0], 1)

# Finding operation
op = res.op

# Printing the result
print('Operation: ', op)

Output:

data:  Tensor("Const:0", shape=(2, 3), dtype=int32)
Operation:  name: "Const"
op: "Const"
attr {
  key: "dtype"
  value {
    type: DT_INT32
  }
}
attr {
  key: "value"
  value {
    tensor {
      dtype: DT_INT32
      tensor_shape {
        dim {
          size: 2
        }
        dim {
          size: 3
        }
      }
      tensor_content: "\001\000\000\000\002\000\000\000\003\000\000\000\004\000\000\000\005\000\000\000\006\000\000\000"
    }
  }
}

Example 2: In this example eager execution is enable so it will raise AttributeError.

Python3

# Importing the library
import tensorflow as tf

# Initializing the input
data = tf.constant([[1, 2, 3], [4, 5, 6]])

# Printing the input
print('data: ', data)

# Calculating result
res = tf.IndexedSlices(data, [0], 1)

# Finding operation
op = res.op

# Printing the result
print('Operation: ', op)

Output:

data:  tf.Tensor(
[[1 2 3]
 [4 5 6]], shape=(2, 3), dtype=int32)
