How to Solve Python AttributeError: module ‘tensorflow’ has no attribute ‘placeholder’
In TensorFlow 2.0, tf.placeholder is no longer in use. A placeholder is a variable that we will assign data to at a later point. It allows us to create operations and build the computation graph without the data. In TensorFlow 2.0, we can use tf.function to execute...
How to Solve Python AttributeError: module ‘tensorflow’ has no attribute ‘Session’
In TensorFlow 2.0, tf.Session is no longer in use. TensorFlow 2.0 encapsulates graph computations as Python functions instead of using Session making TensorFlow more Pythonic. If you want to continue using Session in TensorFlow 2.0, use tf.compat.v1.Session() instead....
How To Solve Python AttributeError: module ‘tensorflow’ has no attribute ‘ConfigProto’
In TensorFlow 2.0, tf.ConfigProto is no longer in use. The functionalities of ConfigProto are now under tf.config.experimental. If you want to continue using ConfigProto in TensorFlow 2.0 use tf.compat.v1.ConfigProto() instead. You can follow the migration guide if...
What is the ‘u’ Before a String in Python?
In Python 2.x, the 'u' in front of string values indicates that the string is a Unicode string. In Python 3, all strings are Unicode by default, and therefore you will not see the 'u' in front of a Unicode string. This tutorial will go through the use of Unicode...
How to Solve Python AttributeError: ‘list’ object has no attribute ‘apply’
The method apply() is a pandas method that applies a function along an axis of a DataFrame. The apply() method does not belong to the List data type. If you try to call the apply() method on a list, you will raise the AttributeError: 'list' object has no attribute...
How to Solve Python ValueError: list.remove(x) x not in list
If you try to remove an element from a list that does not appear in that list, you will raise the ValueError: list.remove(x) x not in list. To solve this error, you can check for list membership using the in operator, for example, if x in a_list. This tutorial will go...
