[BUG] FileNotFoundError: [Errno 2] No such file or directory: 'java'

[mccrindlebrian]

Describe the bug
FileNotFoundError: [Errno 2] No such file or directory: 'java'. Could this issue be related to VS Code, or did OpenJDK not install correctly for Merlion's path dependencies?

To Reproduce
Followed the steps to install openjdk for Ubuntu using:
sudo apt-get install openjdk-11-jdk.

I loaded in my own proprietary dataset and followed the conversion steps:

train_data = TimeSeries.from_pd(private_data_df)
model.train(train_data=train_data)

This results in the following output:

Desktop (please complete the following information):

• Linux pop-os 5.13.0-7620-generic Ubuntu x86_64 x86_64 x86_64 GNU/Linux
• Merlion Version 1.1.3

I suspect you'll need to set the environment variable $JAVA_HOME appropriately, and ensure that java's bin directory is on your $PATH.
