据我所知,我甚至不需要pytz来做我正在做的事情.
我正在使用O'Reilly的书"用Python编程计算机视觉"重新学习python进行图像处理(我也是mac的新手,所以无论如何,如果这是一个愚蠢的问题,我道歉).连同'empire.jpg'图片,我正在尝试运行第16页的脚本,如下所示:
from PIL import Image
from pylab import *
# read image to array
im = array(Image.open('empire.jpg')) # plot the image
imshow(im)
# some points
x = [100,100,400,400]
y = [200,500,200,500]
# plot the points with red star-markers
plot(x,y,'r*')
# line plot connecting the first two points
plot(x[:2],y[:2])
# add title and show the plot
title('Plotting: "empire.jpg"')
show()
但我得到以下输出错误:
File "plotch1.py", line 2, in <module>
from pylab import *
File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/pylab.py", line 1, in <module>
