Hi every one. I am learning DJL(Deep java library) and I have seen Malicious URL Detector post and I'm going to try it locally, but when I run the code I get error.

I have tried to remove FEATURE_LENGTH but got another error:

I want to solve the problem but I don't know how to do it( And I have some questions about source code of Malicious URL Detector line 71 and SequentialBlocks.

1. Why we initialize 3D shape? in csv data only 2 column(first feature and second is label)
2. Why we need a lot of blocks? What does it mean acctually? source code
