win7安装玩64位量化交易常用包talib后，使用时遇到的坑

操作系统：win7-64位，python3.6

由于64位系统不能直接使用pip install ta-lib，所以直接下载轮子文件，地址：https://www.lfd.uci.edu/~gohlke/pythonlibs/#ta-lib

安装完成后突然发现直接使用talib调用方法有问题，PyCharm会报错。
原代码如下：

import tushare as ts
import pandas as pd
import matplotlib.pyplot as plt

sh = ts.get_hist_data('sh')
sh = sh.sort_index()

import talib
ma = talib.MA(sh['close'].values,20) #20日均线

ma1 = pd.DataFrame(ma)
ma1.index = sh.index
sh['mma5'] = ma1

sh[['close','mma5']].plot(figsize = (15,8),grid = True)
plt.show()

修改成如下形式就没问题了：

import tushare as ts
import pandas as pd
import matplotlib.pyplot as plt

sh = ts.get_hist_data('sh')
sh = sh.sort_index()

# import talib
# ma = talib.MA(sh['close'].values,20) #20日均线
from talib import abstract
ma = abstract._ta_lib.MA(sh['close'].values,20) #20日均线

ma1 = pd.DataFrame(ma)
ma1.index = sh.index
sh['mma5'] = ma1

sh[['close','mma5']].plot(figsize = (15,8),grid = True)
plt.show()
