I am attempting to train an Image Classification model in Create ML 2.0 (53.1) on macOS Big Sur 11.0.1. My MacBook Air (from year 2019, with Intel processor, 8GB memory) has around 25GB free space on the internal disk at the beginning of the training. The training dataset is relatively big: around 200.000 images taking 20GB disk space, 800 classes. The images are all stored on an external hard drive. I successfully imported the dataset in Create ML and could start the training. At the stage of extracting image features, however, a temporary file is getting built up and at around 4% of the feature extracting, the 25GB free space on my internal drive gets eaten up and the training stops with an "Unexpected Error". Is there any way to change the temporary file location for Create ML to my external hard disk or any other way to make sure that the training can be finished even in case of low internal hard disk space available?
