How to resolved indentationError: unexpected indent?

Question

如何纠正 python 中的这个错误 "unexpected indent"？

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)

假设这不是复制到 SE 时的复制和粘贴错误，您需要更改第一个缩进 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)
