Description

The custom Logger class in logger.py is missing the warning() method, which causes an AttributeError when api.py attempts to call it.

Error Message

AttributeError: 'Logger' object has no attribute 'warning'

Stack Trace

File "src/depth_anything_3/api.py", line 334, in _align_to_input_extrinsics_intrinsics
    logger.warning(
    ^^^^^^^^^^^^^^
AttributeError: 'Logger' object has no attribute 'warning'

Root Cause

In api.py line 334, the code calls logger.warning():

logger.warning(
    "Pose alignment failed due to insufficient camera motion. "
    "Using model-estimated poses and relative depth."
)

However, the Logger class in logger.py only defines warn(), not warning():

def warn(self, *args, **kwargs):
    self.log("WARN:", *args, **kwargs)

Suggested Fix

Add a warning() method as an alias to warn() in the Logger class to match Python's standard logging module interface:

def warning(self, *args, **kwargs):
    """Alias for warn() to match standard logging interface."""
    self.warn(*args, **kwargs)

Environment

• Using the inference API with external extrinsics/intrinsics alignment
• Error occurs when pose alignment fails due to insufficient camera motion
