@glenn-jocher this line breaks any system that doesn't allow writing on this specific directory.

For example, AWS Lambda Functions only allow writing to /tmp.

This is an issue because when pulling git pull ...ultralytics/yolov5 and running it inside a Lambda function, it will fail with:

Is there a way to configure the directory to which Arial.ttf is written?
