我使用的是Python 3.2.1,我无法导入StringIO模块.我使用 io.StringIO和它的作品,但我不能使用它numpy的genfromtxt是这样的:

x="1 3\n 4.5 8"        
numpy.genfromtxt(io.StringIO(x))

我收到以下错误:

TypeError: Can't convert 'bytes' object to str implicitly  

当我写import StringIO它时说

ImportError: No module named 'StringIO'

我在Visual Studio 2013中运行Python 2.7.代码以前在Spyder中运行正常,但是当我运行时:

import numpy as np
import scipy as sp
import math as mt
import matplotlib.pyplot as plt
import Image
import random

# (0, 1) is N
SCALE = 2.2666 # the scale is chosen to be 1 m = 2.266666666 pixels
MIN_LENGTH = 150 # pixels

PROJECT_PATH = 'C:\\cimtrack_v1'
im = Image.open(PROJECT_PATH + '\\ST.jpg')

我最终得到以下错误:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\cimtrack_v1\PythonApplication1\dr\trajgen.py", line 19, in <module>
    im = Image.open(PROJECT_PATH + '\\ST.jpg') …
