ImportError: cannot import name ‘adam’ from ‘keras.optimizers’

When you are working with neural networks and want to use the keras modules, you might face importerror: cannot import name ‘adam’ from ‘keras.optimizers’ error. The main reason for this error is that the Python script cannot import the adam from keras optimiers. In such cases, it is recommended to use TensorFlow.keras in order to solve the error. In this short article, we will learn how we can solve importerror: cannot import name ‘adam’ from ‘keras.optimizers’ error rising various possible methods. Moreover, we will also discuss how we can understand and interpret errors in Python.

ImportError: cannot import name ‘adam’ from ‘keras.optimizers’

ImportError: cannot import name ‘adam’ from ‘keras.optimizers’ – Possible Solutions

We know that the error is because the Python script could not import the adam from the keras.optimizers. This means that in your code you are trying to import the adam directly from the keras optimizer and it fails to import. The simplest solution is to use tensorflow.keras instead of direct keras.

Let us first take an example and see why we are getting this error:

# importing the adam from keras
from keras.optimizers import adam

Output:

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
/tmp/ipykernel_184126/3757597842.py in <module>
      1 # importing the adam from keras
----> 2 from keras.optimizers import adam

ImportError: cannot import name 'adam' from 'keras.optimizers' (/home/student/.local/lib/python3.10/site-packages/keras/optimizers/__init__.py)

Notice that we got the error that clearly says that the script fails to import the adam optimizer from the keras module.

The following are incorrect way of importing the adam from keras module. If you are using any of the given methods to import the adam from Keras, then you will get the error:

from tensorflow.keras.optimizers import adam 
from keras.optimizers import Adam            
from keras.optimizers import adam

Once you understand the error and the reason for getting the error then it becomes easy to solve the issue. Let us now jump into the possible solutions to solve the error.

Solution-1: Using TensorFlow

The first thing to understand before solving the error is that there are two types of Keras modules:

  1. Keras module
  2. tensorflow.keras module

So, when we are getting ImportError: cannot import name ‘adam’ from ‘keras.optimizers’ error, most probably we are using the Keras module and trying to import the adam from there. The error can be easily solved by importing Adam from the tensorflow.keras module as shown below:

The following is the correct way of importing the Adam module from the Keras module:

# importing the adam from the tensorflow
from tensorflow.keras.optimizers import Adam

Hopefully, this will help you to get rid of the error. If you are getting the error TensorFlow module not found when you run the above command, then you need to first install TensorFlow on your system.

You can choose any of the given commands to install TensorFlow on your system:

# if you are using pip command
pip install tensorflow

# if you are using pip3
pip3 install tensorflow

# if you are using jupyter notebook
!pip install tensorflow

# if you are using conda 
conda install tensorflow

Or you can visit the official page of TensorFlow to know the installation process:

ImportError-cannot-import-name-‘adam-from-‘keras.optimizers

Hopefully, now you can easily import the adam from keras using the above-mentioned method.

Solution-2: Using Keras module

Another way to get rid of the error is to use the Keras module directly to import the adam.

Instead of using the following commands to import the adam:

from keras.optimizers import Adam

The correct way of importing adam from the keras is the following:

from keras.optimizers import adam_v2

optimizer = adam_v2.Adam(learning_rate=lr, decay=lr/epochs)
Model.compile(loss='--',  optimizer=optimizer  , metrics=['--'])

Hopefully, you will no longer get the error.

Understanding the ImportError: cannot import name ‘adam’ from ‘keras.optimizers’ error

As you can see, the error has two main parts that help us to understand and figure it out. The first part of the error is the category of the error which is ImportError. This means there is something wrong with importing the modules. The second part of the error gives more specific details and helps us to figure out which module was not imported. It clearly says that the adam was not imported from the Keras module which means there is a problem with the Keras module.

What is Keras Module?

Keras is a highly, deep API that was developed by google company for implementing Neural Networks. It is written in Python and is used to make the implementation of neural networks easy. It also supports multiple backend neural network computations.

What is Keras.optimizer?

An optimizer is one of the two arguments required for compiling a Keras model: from TensorFlow import keras from tensorflow.keras import layers model = keras. Sequential() model. add(layers. Dense(64, kernel_initializer=’uniform’, input_shape=(10,))) model.

Summary

In this short article, we discussed what is ImportError: cannot import name ‘adam’ from ‘keras.optimizers’ error and the reasons for getting this error. Moreover, we also discussed how to solve the error using various methods
