Attributeerror: module ‘tensorflow’ has no attribute ‘scalar_summary’

In this article, we will discuss how to solve the attributeerror module ‘tensorflow’ that has no attribute ‘scaler_summmary’. Let us discuss how to use the scalar_summary() function in TensorFlow. And we’ll also cover the following topics:

• Attributeerror: module ‘tensorflow’ has no attribute ‘scalar_summary’
• Attributeerror: module ‘tensorflow’ has no attribute ‘scaler’
• Attributeerror: module ‘tensorflow’ has no attribute ‘nest’
• Attributeerror: module ‘tensorflow’ has no attribute ‘Confusion_matrix’

attributeerror: module ‘tensorflow’ has no attribute ‘scalar_summary’

• In this section, we will discuss how to solve the attributeerror module ‘tensorflow’ has no attribute ‘scalar_summary’.
• This name, prefixed by any active name scopes, will be the summary tag used for TensorBoard.

Example:

import tensorflow as tf
tf.compat.v1.disable_eager_execution()
tf.compat.v1.reset_default_graph()   

new_scalar_value = tf.compat.v1.get_variable('x_scalar' , shape=[], initializer=tf.compat.v1.truncated_normal_initializer(mean=0, stddev=1))

new_summary_scalar = tf.scalar_summary(name='scaler_value_first', tensor=new_scalar_value )

new_initializer = tf.global_variables_initializer()

with tf.compat.v1.Session() as val:

    writer = tf.summary.FileWriter('./graphs', val.graph)
    for step in range(50):
        
        val.run(new_initializer)
        
        summary = val.run(new_summary_scalar)
        writer.add_summary(summary, step)
    print('Done with the new_scalar summary')

In the following given code, we imported the tensorflow library with the alias name ‘tf’ and then used the tf.compat.v1.get_variable() function and this function tf.get variable() produces a variable with the requested shape and initializer if one does not already exist and returns the variable with the requested shape and initializer if one does not already exist.

Here is the implementation of the following given code

Here is the Solution to this error

Reason: The reason for this error is tf.scalar_summary() function is not available in Tensorflow any version. Now in this case we use the tf.s ummary.scalar() function.

Syntax:

tf.summary.scalar(
                  name, 
                  data, 
                  step=None,
                  description=None
                 )

• It consists of a few parameters
  • name: The title of this summary. This name plus any current name scopes will be the summary tag for TensorBoard.
  • data: a real scalar number that can be converted to a float32 tensor.
  • step: It explicit int64 and monotonic step value for this summary. By default, it takes none value.
  • Description: By default, it takes none value and it is a long-form description for this summary.

import tensorflow as tf
tf.compat.v1.disable_eager_execution()
tf.compat.v1.reset_default_graph()   

new_scalar_value = tf.compat.v1.get_variable('x_scalar' , shape=[], initializer=tf.compat.v1.truncated_normal_initializer(mean=0, stddev=1))

new_summary_scalar =tf.summary.scalar(name='scaler_value_first', tensor=new_scalar_value )

new_initializer = tf.global_variables_initializer()

with tf.compat.v1.Session() as val:

    writer = tf.summary.FileWriter('./graphs', val.graph)
    for step in range(50):
        
        val.run(new_initializer)
        
        summary = val.run(new_summary_scalar)
        writer.add_summary(summary, step)
    print('Done with the new_scalar summary')

In this example, we used the tf.summary.scalar() function and within this function, we assigned the name of the summary and tensor name. Next, we will be creating the writer inside the session. In the end, add the summary to the writer.

You can refer to the below Screenshot

This is how to solve the attributeerror module tensorflow has no attribute scalar_summary.

attributeerror: module ‘tensorflow’ has no attribute ‘scaler’

• Here we will discuss how to solve the attributeerror module ‘tensorflow’ has no attribute session.
• A scalar type of tensor means is produced by the scalar() function. A scaler, also known as a rank-0 Tensor, is a zero-dimension array. Using the scalar() function, a scalar is produced.

Example:

import tensorflow as tf
tf.compat.v1.disable_eager_execution()
tf.compat.v1.reset_default_graph()   

new_scalar_value = tf.compat.v1.get_variable('x_scalar' , shape=[], initializer=tf.compat.v1.truncated_normal_initializer(mean=0, stddev=1))

new_summary_scalar =tf.scalar.summary(name='scaler_value_first', tensor=new_scalar_value )

new_initializer = tf.global_variables_initializer()

with tf.compat.v1.Session() as val:

    writer = tf.summary.FileWriter('./graphs', val.graph)
    for step in range(50):
        
        val.run(new_initializer)
        
        summary = val.run(new_summary_scalar)
        writer.add_summary(summary, step)
    print('Done with the new_scalar summary')

Here is the Screenshot of the following given code

The solution to this error

In this example we are going to use the tf.math.scalar_mul() function.

Syntax:

tf.math.scalar_mul(
                   scalar,
                   x,
                   name=None
                 )

• It consists of a few parameters
  • scalar: This parameter specifies the known shape.
  • x: This defines the input tensor or indexed slices to be scaled.
  • name: By default, it takes none value and specifies the name of the operation.

import tensorflow as tf 
new_tensor = tf.reshape(tf.range(20, dtype=tf.float32), [10, 2])
with tf.GradientTape() as w:
  w.watch(new_tensor)
  m = tf.gather(new_tensor, [2, 3]) 
  result = tf.math.scalar_mul(20.0, m)
  print(result)

In the following given code we used the tf.reshape() function To reshape a given tensor into the desired shape, use the tf.reshape() function. Next, we used the tf.math.scalar_mul() and thus multiplies a scalar times.

You can refer to the below Screenshot

As you can see in the Screenshot we have solved the attributeerror module tensorflow has no attribute scaler.

attributeerror: module ‘tensorflow’ has no attribute ‘nest’

• Let us discuss how to solve the attributeerror module ‘tensorflow’ has no attribute ‘nest’.
• To perform this task we are going to use the tf.Nest() function and a value of any other type, usually one of the compatible types like int, float, ndarray, or a TensorFlow data type like Tensor, Variable. commonly referred to as the structure’s atoms.

Example:

import tensorflow as tf
result= tf.Nest.is_nested("1234")
print(result)

Here is the implementation of the following given code

The solution to this error

Reason: The reason behind this error is the tf.Nest() function does not work in the Tensorflow version and this function has been modified in the latest version of tensorflow 2.9 which is tf.nest().

Source Code:

import tensorflow as tf
result= tf.nest.is_nested("7564")
print(result)

You can refer to the below Screenshot

This is how to solve the attributeerror module tensorflow has no attribute nest

attributeerror: module ‘tensorflow’ has no attribute ‘Confusion_matrix’

• In this section, we will discuss how to solve the attributerror module ‘tensorflow’ has no attribute ‘confusion_matrix’.
• In Python TensorFlow, the confusion matrix is used to find the confusion matrix from predictions and labels.
• A table called a confusion matrix is used to describe how well a classification system performs. The output of a classification algorithm is visualized and summarised in a confusion matrix.

Syntax:

Let’s have a look at the Syntax and understand the working of the tf.confusion_matrix() function

tf.math.confusion_matrix(
    labels,
    predictions,
    num_classes=None,
    weights=None,
    dtype=tf.dtypes.int32,
    name=None
)

• It consists of a few parameter
  • labels: For the classification task, a 1-D tensor of real labels is used.
  • prediction: This parameter defines the prediction for the given classification.
  • num_classes: This parameter defines how many labels a classification task would be able to use. If this value is not specified, it will be determined using the labels array and predictions.
  • weights: By default, it takes none value and it will check the shape matches predictions.
  • dtype: By default it takes tf.dtypes.int32() and it specifies the data type of the confusion matrix.

Example:

import tensorflow as tf

new_label_val = tf.constant([2,6,7],dtype = tf.int32)
new_predict_val = tf.constant([15,78,2],dtype = tf.int32)

# Evaluating confusion matrix
new_output = tf.Confusion_matrix(new_label_val,new_predict_val)

# Printing the result
print('Confusion_matrix: ',new_output)

Here is the implementation of the following given code

Here is the Solution to this error

Reason: The reason for this error this function is not available in TensorFlow’s latest version and this function takes a few parameters.

import tensorflow as tf

new_label_val = tf.constant([2,6,7],dtype = tf.int32)
new_predict_val = tf.constant([15,78,2],dtype = tf.int32)

# Evaluating confusion matrix
new_output = tf.confusion_matrix(new_label_val,new_predict_val)

# Printing the result
print('Confusion_matrix: ',new_output)
