使用TA-lib遇到ImportError：无法导入名称'__TA_FUNCTION_NAMES__'

Question

有人遇到过Ta-lib问题吗？我无法导入任何功能，该库似乎已正确安装（从.whl文件安装，使用pip列表进行了检查）：

import talib

feature_names = ['5d_close_pct']

# Create moving averages and rsi for timeperiods of 14, 30, 50, 200

list_of_timeperiods = [14, 30, 50, 200]
for n in list_of_timeperiods:

    # Create the moving average indicator and divide by Adj_Close
    returns_data['ma' + str(n)] = talib.SMA(returns_data['Adj_Close'].values, timeperiod=n)/returns_data['Adj_Close']

    # Create the RSI indicator
    returns_data['rsi' + str(n)] = talib.RSI(returns_data['Adj_Close'].values, timeperiod=n)

    # Add RSI and MA to the feature name list
    feature_names = feature_names + ['ma' + str(n), 'rsi' + str(n)]

print (feature_names)
