如何解决indentationError：意外缩进？

Question

How do I rectify this error "unexpected indent" in python?

from fast_rcnn.config import cfg
from nms.cpu_nms import cpu_nms

def nms(dets, thresh, force_cpu=False):
    """Dispatch to either CPU or GPU NMS implementations."""

    if (dets.shape[0]) == 0:
     return []

    return cpu_nms(dets, thresh)

Assuming this is not a copy and paste error when copying into SE, you need to change the indentation for your first return:

from fast_rcnn.config import cfg
from nms.cpu_nms import cpu_nms

def nms(dets, thresh, force_cpu=False):
    """Dispatch to either CPU or GPU NMS implementations."""

    if (dets.shape[0]) == 0:
        # Note the changed indentation here
        return []

    return cpu_nms(dets, thresh)
