python-2.7 - Mtaplotlib 属性错误 : 'module' object has no attribute 'pyplot'

Question

在有人说“重复问题”或任何其他问题之前，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

在哪里

$ 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

我使用的是 matplotlib 1.2 版；

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

我尝试了几种方法来让它工作；

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

他们都没有工作。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

    import matplotlib.pyplot as plt
AttributeError: 'module' object has no attribute 'pyplot'

真正令人沮丧的是，我有另一个文件，带有 from matplotlib import pyplot as plt在顶部，它工作正常。我看不出有任何理由为什么一个会工作而另一个不会......

我也尝试更改文件名，使其不是 numbers.py但这也不起作用。

有没有人以前遇到过这个问题并解决了它？或者知道为什么它不起作用？

这是完整的文件:

from matplotlib import pyplot as plt

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

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

    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:

    elif number == 0:
        return "zero"

    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()

您正在隐藏系统文件并获得循环导入。

请注意，回溯的第一个和最后一个文件正在尝试从同一文件导入。

将文件名更改为其他名称(并删除 pyc 文件)，它应该可以工作。

另见 matplotlib not working anymore due to interactive issue这有一个类似的问题。
