How To Manage ML Experiments With banner is a lightweight tool for experiment management and collaboration in Data Science projects. It is an organized place for all your experiments, data exploration Notebooks and more. It supports any kind of project workflow. One can use it individually or in a team. Moreover, it can be utilized as a service or can be deployed on your hardware or the cloud as well. It features Notebooks’ tracking and versioning capabilities so you will never lose your data exploration insights or other crucial information related to the project. was introduced to the world by a private organization named Neptune Labs Inc in November 2017. The company has its headquarters at Warsaw, Mazowieckie (Poland) and was founded by Piotr Niedzwiedz

Some of the reputed companies which leverage to manage their ML experiments include:

Following are some of the vital use cases of the tool:

  1. Organize the workflow of your project (How?)
  2. Monitor each run of the experiment (How?)
  3. Share the experiment’s outcomes with your team (How?)
  4. Clean up your project’s workflow (How?)

Demo code


Installing using Python requires Python 3.x installed on your machine. Run the following command to install neptune-client :

pip install neptune-client

Import required libraries

 import neptune
 import numpy as np
 from time import sleep 

Initialize Neptune

Create Neptune experiment


 Log metrics to experiment

 from time import sleep
 neptune.log_metric('single_metric', 0.62)
 for i in range(50):
     sleep(0.15)  #watch live logging
     neptune.log_metric('random_training_metric', i * np.random.random())
     neptune.log_metric('other_random_training_metric', 0.4 * i * np.random.random()) 

The output of the above lines of code includes a link to our experiment in Neptune where we can explore our experiment through various visualization charts, logs, artifacts (arbitrary files) and so on.

Practical implementation of a Deep Learning experiment using

Import required libraries

 import neptune
 import tensorflow as tf 

Load the MNIST dataset

 data = tf.keras.datasets.mnist
 (x_train, y_train), (x_test, y_test) = data.load_data() 

Normalize the data

X_train, x_test = x_train / 255.0, x_test / 255.0

Define the model

 model = tf.keras.models.Sequential([ tf.keras.layers.Flatten(),
         tf.keras.layers.Dense( 256, activations =        
         tf.keras.layers.Dense( 10, activations =       
         tf.keras.activations.softmax) ]) 

Define the optimizers

opt = tf.keras.optimizers.SGD(lr=0.005, momentum=0.4,)

Compile the model


Initialize Neptune


Create a Neptune experiment


Fit the model to training data, y_train,

Running the above lines of code will give a link to the Neptune UI as output where you can explore your experiment.

Log hardware consumption of the experiment

pip install --quiet psutil==5.6.6

Log hyperparameters of the neural network

 #Define the hyperparameters
 parameters = {'lr':0.005, 

The procedure to compile and fit the model remains the same. The only additional thing here is to add the above defined parameters to the create_experiment() call.

neptune.create_experiment('tensorflow-keras-advanced', params=parameters)

Log the predictions

 #Select an image from the test set
 x_test_sample = x_test[:10]
 #Predict the label of sample
 y_test_sample_pred = model.predict(x_test_sample)
 #Log the prediction
 for image, y_pred in zip(x_test_sample, y_test_sample_pred):
     desc = '\n'.join(['class {}: {}'.format(i, pred)
                                 for i, pred in enumerate(y_pred)])

Save the model'MODEL_NAME')

Log the model weights


Explore the results in Neptune UI and stop logging at the end.



Find the Google Colab notebook of the above implementation code here. Integrations

Neptune provides integrations with over 25 Python libraries widely used for a variety of real-world AI/ML applications.Some of the integrations written using neptune-client include Pandas, Matplotlib, Pyplot, Pytorch, TensorFlow, Keras, Scikit-learn, Scikit Optimize, XGBoot and so on. The complete list of available integrations can be found here

Run ML experiments anywhere using

An ML experiment can be run in any environment and log it to Neptune. There is a simple two-step process to do so using Python.

  1. Install Neptune client

pip install neptune-client

  1. Add logging code 

For instance,

 import neptune
 # training logic
 neptune.log_metric('accuracy', 0.95) 

Multi-language support

Neptune supports experiments written using multiple programming languages. 

See how it works with Python, R or any other language.

Notebook flavours supported by

EndNote provides an efficient way to store, visualize, organize and compare the metadata associated with an ML experiment. It is a prominent MLOps solution that smoothens the ML workflow by making your project easily manageable irrespective of whether it is handled individually or collaboratively.
