Common Errors and Debugging

In this chapter, we will be working through common errors that you will be presented with as a newly qualified graph data scientist or engineer (which you will be when you have finished reading this book). The focus will be on how to debug graph issues. This will lead on to common issues and how to get around them when working in igraph. Following on from this, we will look at common Neo4j issues, as we have been working igraph, Python, and Neo4j for a large proportion of this book; therefore, it is useful to know how to get around graph database issues as well. We will also touch on how to modify your igraph and Neo4j scripts to achieve the best performance.

There are many examples under each of these sections, with use cases of how and why these issues may present themselves. Therefore, you will be perfectly prepared, after reading this chapter, to debug and solve these common issues in your projects. In the upcoming sections, you will delve into common...
