Question

在有人说“重复的问题”之前，请继续阅读，这与其他问题不同。

所以当我运行我的小程序时;

python numbers.py

，其中

$ file `which python`
/usr/bin/python: symbolic link to 'python2.7'

$ file `which python2.7`
/usr/bin/python2.7: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=0x623b662458af705775fcbd2576ca06eaa82bc482, stripped

我正在使用matplotlib版本1.2;

/usr/local/lib/python2.7/dist-packages/matplotlib-1.2.0-py2.7-linux-x86_64.egg/

我尝试了几种方法让它发挥作用;

from matplotlib import pyplot as plt
import matplotlib.pyplot as plt

它们都不起作用。他们都给出了同样的错误;

$ python numbers.py
Traceback (most recent call last):
  File "numbers.py", line 1, in <module>
    import matplotlib.pyplot as plt

真正令人沮丧的是，我有另一个文件，顶部有from matplotlib import pyplot as plt，它运行正常。我看不出为什么一个人会工作而另一个人不会......

我也尝试更改文件名，因此它不是numbers.py，但也没有“工作”。

有没有人遇到这个并修复过它？或者知道它为什么不起作用？

这是完整的文件：

from matplotlib import pyplot as plt

    if type(number) == float:
        return floatToString(number)
    elif type(number) == int:
        return intToString(number)

    if number < 0:
        return "minus " + intToStringPos(abs(number))

    tenTimes = "twenty thirty fourty fifty sixty seventy eighty ninety hundred".split()
    logs = [""] + "thousand million billion trillion quadrillion".split()

    if len(str(number)) > 3:
        #split number into groups of three, from the right hand end    
        number = list(reversed(str(number)))

        groups = list(reversed([int("".join(reversed([number[i+j] for j in range(3) if i+j < len(number)]))) for i in range(0, len(number), 3)]))

            else:
                retString = intToString(number) + " " + logs[i] + " " + retString

        return retString.strip()

    elif 1000 > number > 99:
        tens = intToString(int(str(number)[1:]))
        if tens != "zero":
            return upTo20[number/100] + " hundred and " + tens
        else:

    elif 0 < number < 20:
        return upTo20[number]

    elif number == 0:
        return "zero"

def floatToString(number):

    retString = intToString(int(integerPart))
    if decimalPart > 0.0:
         return retString + " point " + " ".join([intToString(int(d)) for d in str(decimalPart)[2:]])
    else:
         return retString

def complexToString(number):
    retString = []
    if number.real > 0.0:
        retString.append(floatToString(number.real))
    if number.imag > 0.0:
        if number.imag == 1:
            retString.append("j")
        else:
            retString.append(floatToString(number.imag) + " j")

    return " plus ".join(retString)


lengths = []
for number in range(1000):
    print toString(number)      
    lengths.append(len(toString(number)))

print lengths

plt.plot(range(1000), lengths)
plt.pyplot.show()

Answer 1

您正在镜像系统文件并获得循环导入。

请注意，追溯的第一个和最后一个文件正在尝试从同一个文件导入。

将文件名更改为其他名称（并删除pyc文件），它应该有效。
