以下代码在我的桌面 (Mint 17) 上运行时没有任何问题,但是当我尝试在运行 Raspbian 的 RPi 上运行它时,我在第 58 行收到上述错误消息。我认为这是造成它的唯一原因是Python版本:
Mint 使用 Python 2.7.6
$ python -V
Python 2.7.6
RPi 使用 2.7.3,但我安装了 2.7.8 并为其取了别名
$ python -V
Python 2.7.3
$ alias python=/usr/local/bin/python2.7
$ python -V
Python 2.7.8
我知道这里有类似的问题,但在这些情况下问题似乎与代码相关。我知道这段代码没问题,所以一定是环境问题吧?
无论如何,这是程序:
#!/usr/bin/env python
# Determines if a set of three images contains at least one person
# Images are taken in quick succession, the 2nd and 3rd are diff images of the first
# Adapted from sample file: /opencv/samples/python2/peopledetect.py

# Example: ./pdTriple.py IMG_000.JPG IMG_001.JPG IMG_002.JPG

if img is None:

continue
except:
print 'loading error'
continue
# modify winstride and padding values to optimise results
found, w = hog.detectMultiScale(img, winStride=(4,4), padding=(8,8), scale=1.05)
found_filtered = []
for ri, r in enumerate(found):
for qi, q in enumerate(found):
if ri != qi and inside(r, q):uname # errors here
break
else:
found_filtered.append(r)
print '%d found (%d filtered)' % (len(found_filtered), len(found))
results[count] = len(found_filtered)
count += 1
if np.all(results>0):
print '\n--------------', fn, 'contains a person --------------\n'
最佳答案
如果你删除'uname',它会起作用;
for ri, r in enumerate(found):
for qi, q in enumerate(found):
if ri != qi and inside(r, q): # errors here
break
else:
found_filtered.append(r)
