 Nowadays, LSTMs have been replaced by the [Transformer](https://jalammar.github.io/illustrated-transformer/)( which uses [Attention](https://jalammar.github.io/visualizing-neural-machine-translation-mechanics-of-seq2seq-models-with-attention/) to tackle all the problems that plague an LSTM such as as lack of [transfer learning](https://en.wikipedia.org/wiki/Transfer_learning), lack of [parallel training](https://web.stanford.edu/~rezab/classes/cme323/S16/projects_reports/hedge_usmani.pdf) and a long gradient chain for lengthy sequences
 
-Building a neural network from scratch with NumPy is a great way to learn more about NumPy and about deep learning. However, for real-world applications you should use specialized frameworks — such as PyTorch, JAX, TensorFlow or MXNet — that provide NumPy-like APIs, have built-in automatic differentiation and GPU support, and are designed for high-performance numerical computing and machine learning.
