Step 3: Choose your image

Click Select Image. Choose pytorch/pytorch . For version tag to use choose the one that starts with nightly_devel_cuda9.2

Step 4: Choose whether to rent or bid

Accept a price and start by pressing Rent on the machine of your choice. Or make a Make Bid to bid on a machine. If you a make a bid and then someone rents the machine at the full price, you loose out. Renting leads to less frustration than bidding.

What is fastai library?

fastai is a deep learning library which provides practitioners with high-level components that can quickly and easily provide state-of-the-art results in standard deep learning domains, and provides researchers with low-level components that can be mixed and matched to build new approaches. It aims to do both things without substantial compromises in ease of use, flexibility, or performance. This is possible thanks to a carefully layered architecture, which expresses common underlying patterns of many deep learning and data processing techniques in terms of decoupled abstractions. These abstractions can be expressed concisely and clearly by leveraging the dynamism of the underlying Python language and the flexibility of the PyTorch library. fastai includes:
