【问题描述】：
我已经为 python 2.7.4 安装了 matplotlib 1.2.0 和 numpy 1.6.2 当我尝试运行我的代码时，我收到以下导入错误。
Traceback (most recent call last):

allTypes[alias] = allTypes[t]
KeyError: 'timedelta'
产生这个错误的部分代码是
import math
import struct
import binascii
from ast import literal_eval
import matplotlib.pyplot as plt
from numpy.fft import fft, fftfreq
import scipy as sp
我觉得它与 numpy 包有关。我错过了什么？！
【问题讨论】：
-
请向我们展示您产生此错误的代码。向我们展示文件
D:\Python\IQ_polar.py。 -
现在在问题中展示了它
-
我怀疑这可能是由于 numpy 1.6.2 和 matplotlib 1.2.0 之间的版本不兼容（numpy 1.6.2 相当旧）。您可以尝试更新到更新的版本吗？
-
matplotlib 1.2.0 也相当老了。
