How to use Apache Spark and Horovod for scaling Deep Learning Models on E2E Cloud?

November 24, 2020

Apache Spark and Deep Learning

In any deep learning pipeline, there are two different phases. One involves handling data, and the second is training on that data. Training deep learning models is quite different from most of the problems that we solve with Apache Spark. With Spark, it is possible to handle data quite well. There are many functions available with Spark to pre-process data. The Deep learning model step follows the basic ETL (Extract-Transform-Load) step of Apache. At the model training step, Apache’s basic functions start failing at distributed computations. However, there is an approach available. 

Distributed Deep Learning

One of the approaches used for early distributed deep learning with Spark is through the concept of Parameter servers. There are two concepts for this. One is to use model parallelism. It means to split the layers into different GPU machines and send the weights to the next layer machine. The second is using Data parallelism. In this, the data is split into subsets, and each GPU machine trains on each such subset. The weight is then aggregated using the parameter servers, and the global weight is then sent to each GPU back. There are two main advantages to using parameter servers for distributed training. One is fault tolerance. As the model architecture is copied, there can be backups for the same. It allows for the window of failure on one or more GPUs. Second is the support for asynchronous SGD (Stochastic Gradient Descent). This technique allows the developer to train single instances over different frequencies in any of the machines. But it is not all perfect. There are some serious limitations to this approach. 

Limitations with the approach

The first problem of using parameter servers is that they are complex to implement. The usability has been an issue since the introduction of the method. The developers need to scaffold a lot of code to integrate parameter server associated training securely. The problem with distributed training is the efficiency of scale. If it is not set right, there is no use in using multiple machines at all. One other problem with the approach is that parameter servers mostly end up in a major bottleneck. Now one of the advantages of parameter servers is also a disadvantage sometimes. The asynchronous SGD can be advantageous many times but is less preferred on different frequencies as it typically leads to degradation and model convergence. So in practice, it is preferred to have all individual machines operating at the same frequency, even though asynchronous SGD allows for running on different frequencies. 

Horovod

Looking at the limitations of the current frameworks, which were mostly implemented based on parameter networks, folks at Uber developed an elegant solution – Horovod. Before we go into the details of the technique of Horovod, here are a few of the advantages of using this framework. 

  • Minimal code: With Horovod, setting up a distributed deep learning pipeline can be done using as low as just five lines of code. 
  • High performance: It allows us to integrate all the high-performance features like Nvidia’s Nickel, GPUDirect, as well as RDMA. 
  • Framework support: It supports all the frameworks running on Spark in addition to Tensorflow, PyTorch, Keras, as well as ApacheMXNet.
  • Ease of installation: As it is all in one package, the installation required is only to type one command – pip install Horovod. That’s it. 

Now, what does Horovod do differently that makes it so efficient in scaling deep learning training? Horovod uses a decentralized technique known as AllReduce. In this technique, at each step, the computation is made in every GPU and weights are propagated to the next machine. It makes it easier to set up and update the global parameter at each iteration. It also makes the training a bit faster and effective at scaling. The decentralized structure can be a ring, or a tree, whichever way it is most efficient and also depending on how Nickel wants to optimize it. 

To use Horovod for scaling the Deep learning models, add the KerasEstimator of the Horovod package, into the basic Spark pipeline, and Horovord and Spark from there will handle everything.

Project Management for AI-ML-DL Projects

Managing a project properly is one of the factors behind its completion and subsequent success. The same can be said for any artificial intelligence (AI)/machine learning (ML)/deep learning (DL) project. Moreover, efficient management in this segment holds even more prominence as it requires continuous testing before delivering the final product.

An efficient project manager will ensure that there is ample time from the concept to the final product so that a client’s requirements are met without any delays and issues.

How is Project Management Done For AI, ML or DL Projects?

As already established, efficient project management is of great importance in AI/ML/DL projects. So, if you are planning to move into this field as a professional, here are some tips –

  • Identifying the problem-

The first step toward managing an AI project is the identification of the problem. What are we trying to solve or what outcome do we desire? AI is a means to receive the outcome that we desire. Multiple solutions are chosen on which AI solutions are built.

  • Testing whether the solution matches the problem-

After the problem has been identified, then testing the solution is done. We try to find out whether we have chosen the right solution for the problem. At this stage, we can ideally understand how to begin with an artificial intelligence or machine learning or deep learning project. We also need to understand whether customers will pay for this solution to the problem.

AI and ML engineers test this problem-solution fit through various techniques such as the traditional lean approach or the product design sprint. These techniques help us by analysing the solution within the deadline easily.

  • Preparing the data and managing it-

If you have a stable customer base for your AI, ML or DL solutions, then begin the project by collecting data and managing it. We begin by segregating the available data into unstructured and structured forms. It is easy to do the division of data in small and medium companies. It is because the amount of data is less. However, other players who own big businesses have large amounts of data to work on. Data engineers use all the tools and techniques to organise and clean up the data.

  • Choosing the algorithm for the problem-

To keep the blog simple, we will try not to mention the technical side of AI algorithms in the content here. There are different types of algorithms which depend on the type of machine learning technique we employ. If it is the supervised learning model, then the classification helps us in labelling the project and the regression helps us predict the quantity. A data engineer can choose from any of the popular algorithms like the Naïve Bayes classification or the random forest algorithm. If the unsupervised learning model is used, then clustering algorithms are used.

  • Training the algorithm-

For training algorithms, one needs to use various AI techniques, which are done through software developed by programmers. While most of the job is done in Python, nowadays, JavaScript, Java, C++ and Julia are also used. So, a developmental team is set up at this stage. These developers make a minimum threshold that is able to generate the necessary statistics to train the algorithm.  

  • Deployment of the project-

After the project is completed, then we come to its deployment. It can either be deployed on a local server or the Cloud. So, data engineers see if the local GPU or the Cloud GPU are in order. And, then they deploy the code along with the required dashboard to view the analytics.

Final Words-

To sum it up, this is a generic overview of how a project management system should work for AI/ML/DL projects. However, a point to keep in mind here is that this is not a universal process. The particulars will alter according to a specific project.
