"""
Allows to split a dictionary into chunks of equal size. If the length of the dictionary is not divisible by the chunk
size, the last chunk will be smaller. For example, if the length of the dictionary is 10 and the chunk size is 4,
then we'll have three chunks: two of size 4 and one of size 2.

The first function returns a list with the dictionaries and the second one creates a generator.

java.lang.ClassNotFoundException: javafx.util.Pair happens because javafx.util.Pair and other classes from javafx.util are not included in OpenJDK. Options for resolving:

Install java-openjfx

Install java-openjfx through your package manager. (or whatever means you used to install Java on your machine) Note that java-openjfx is compatible with OpenJDK8, not previous versions.

After installing java-openjfx, you may have to add it manually to your IDE SDK classpath. Eg in IntelliJ, you may have to go to Project Structure | SDKs | <select your SDK> | Classpath | + (the Classpath +, not the SDKs +) | and add /usr/lib/jvm/java-8-openjdk/jre/lib/ext/jfxrt.jar (which should be there now that java-openjfx has been installed) | OK
