'raw training dataset split into feature and target for basic neural networks

I am building a neural network model where I'm using a raw txt file training dataset that I'd like to split into features and target, I have used these lines of coding

xtrain = train_data[:,:4]
ytrain = train_data[:,:4]

in which resulted in an error

IndexError: too many indices for array: array is 1-dimensional, but 2 were indexed

my training dataset looks something like this enter image description here

is there any other way that enables me to split this kind of training data?
