  With a wide range of libraries focused on the machine learning market, such
as TensorFlow, NumPy, Pandas, Keras, and others, Python has made a name for
itself as one of the main programming languages. In February 2021, Jos\'e Valim
and Sean Moriarity published the first version of the Numerical Elixir (Nx)
library, a library for tensor operations written in Elixir. Nx aims to allow
the language be a good choice for GPU-intensive operations. This work aims to
compare the results of Python and Elixir on training convolutional neural
networks (CNN) using MNIST and CIFAR-10 datasets, concluding that Python
achieved overall better results, and that Elixir is already a viable
alternative.
