If you are just doing a couple of experiments then using a cloud service provider such as Amazon, Google, or FloydHub for a time-based usage charge is the way to go.

Alternatively, you may build one, buy one ( as I did), or rent one in the cloud (as I still do today). It is common to share high-end GPU machines at universities and companies. Be sure to check out this developer page. It is worth getting familiar with their lineup of products (hardware and software) so you know what you’re paying for if you’re using an instance in the cloud or building a machine yourself. NVIDIA is the market leader in deep learning hardware, and quite frankly the primary option I recommend if you are getting in this space. Graphics Processing Units are great at deep learning for their parallel processing architecture - in fact, these days there are many GPUs built specifically for deep learning - they are put to use outside the domain of computer gaming. If you’ve reached this point, you are likely serious about deep learning and want to train your neural networks with a GPU. Let’s go ahead and get started! Setting up Ubuntu 16.04 + CUDA + GPU for deep learning with Python If you have an NVIDIA CUDA compatible GPU, you can use this tutorial to configure your deep learning development to train and execute neural networks on your optimized GPU hardware.
