List of environment variables

1. Global Variables

2. File Specific Variables

That control tinygrad behavior. This is a list of environment variable that control the runtime behavior of tinygrad and its examples. Most of these are self-explanatory, and are usually used to set an option at runtime.

Example: GPU=1 DEBUG=4 python3 -m pytest

However you can also decorate a function to set a value only inside that function.

# in tensor.py (probably only useful if you are a tinygrad developer)
@Context(DEBUG=4)
def numpy(self) -> ...

Or use contextmanager to temporarily set a value inside some scope:

with Context(DEBUG=0):
  a = Tensor.ones(10, 10)
  a *= 2
