Are there ready-made two-layer neural networks?

Question

Neural networks

The task is as follows: there is a training sample whose elements are an n-dimensional input vector and an m-dimensional output vector. It is required to train the neural network and, as a result, be able to get approximate values ​​of the input vector from the output vector. The work supervisor advised using the network as a "black box", that is, finding a ready-made copy and training it with a sample.
We need a ready-made two-layer perceptron, but I could not find a ready-made one.
I am very limited in time, so I will be grateful for a quick answer.
