Mtaplotlib AttributeError: 'module' object has no attribute 'pyplot'

Before anyone says "duplicate question" or anything, please read on, it's not the same as other questions. So when i run my small program; ``` python numbers.py ``` where ``` $ 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 ``` and i'm using matplotlib version 1.2; ``` /usr/local/lib/python2.7/dist-packages/matplotlib-1.2.0-py2.7-linux-x86_64.egg/ ``` I have tried several approaches to get it to work; ``` from matplotlib import pyplot as plt import matplotlib.pyplot as plt ``` neither of them work. they both give the same error; ``` $ python numbers.py Traceback (most recent call last): File "numbers.py", line 1, in <module> import matplotlib.pyplot as plt File "/usr/local/lib/python2.7/dist-packages/matplotlib-1.2.0-py2.7-linux-x86_64.egg/matplotlib/pyplot.py", line 26, in <module> from matplotlib.figure import Figure, figaspect File "/usr/local/lib/python2.7/dist-packages/matplotlib-1.2.0-py2.7-linux-x86_64.egg/matplotlib/figure.py", line 34, in <module> import matplotlib.colorbar as cbar File "/usr/local/lib/python2.7/dist-packages/matplotlib-1.2.0-py2.7-linux-x86_64.egg/matplotlib/colorbar.py", line 29, in <module> import matplotlib.collections as collections File "/usr/local/lib/python2.7/dist-packages/matplotlib-1.2.0-py2.7-linux-x86_64.egg/matplotlib/collections.py", line 23, in <module> import matplotlib.backend_bases as backend_bases File "/usr/local/lib/python2.7/dist-packages/matplotlib-1.2.0-py2.7-linux-x86_64.egg/matplotlib/backend_bases.py", line 51, in <module> from PIL import Image File "/usr/local/lib/python2.7/dist-packages/PIL/Image.py", line 90, in <module> import numbers File "/home/will/Documents/python/numbers/numbers.py", line 1, in <module> import matplotlib.pyplot as plt AttributeError: 'module' object has no attribute 'pyplot' ``` What is really frustrating, is that i have another file, with `from matplotlib import pyplot as plt` at the top, and it works fine. I can't see any reason why one would work and the other wouldn't... I tried changing the file name too, so that it wasn't `numbers.py` but that didnt' work either. Has anyone come across this before and fixed it? Or know why it doesn't work? Here's the full file: ``` from matplotlib import pyplot as plt def toString(number): if type(number) == float: return floatToString(number) elif type(number) == int: return intToString(number) elif type(number) == complex: return complexToString(number) else: return "NaN" def intToString(number): if number < 0: return "minus " + intToStringPos(abs(number)) else: return intToStringPos(number) def intToStringPos(number): upTo20 = [""] + "one two three four five six seven eight nine ten eleven twelve thirteen fourteen fifteen sixteen seventeen eighteen nineteen".split() 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)])) retString = "" for i, number in enumerate(reversed(groups)): if number == 0: continue elif i == 0 and len(str(number)) < 3: if number != 0: retString = "and " + intToString(number) 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: return upTo20[number/100] elif 100 > number >= 20: return tenTimes[number/10-2] + " " + upTo20[number - 10*(number/10)] elif 0 < number < 20: return upTo20[number] elif number == 0: return "zero" def floatToString(number): integerPart, decimalPart = divmod(number,1) 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() ```
