您可以使用 talib 和 btalib 库中内置的函数来计算许多指标。逐个指标收集所有信息会很麻烦。有没有办法立即做到这一点？如果是这样，我应该如何在 python 中继续这样做？

码：

   def macd(prices):
        print "Running MACD"
        prices = np.asarray(prices)
        print prices
        macd, macdsignal, macdhist = MACD(prices, fastperiod=12, slowperiod=26, signalperiod=9)
        print "MACD "+macd

说明：

我正在尝试对包含收盘价的Python列表进行一些分析。

我知道在将列表交给TA-Lib之前，我必须先对其进行转换，因为我已经看到了所有示例在做的事情。

但是，这可以通过 only length-1 arrays can be converted to Python scalars

我在运行我的代码时收到此错误。主要问题是 hplot 没有正确导入。

  File "MACD.py", line 10, in <module>
  from bokeh.plotting import figure, show, output_file, hplot
  ImportError: cannot import name hplot

这是我的代码：

macds = macd, macdsignal, macdhist = MACD(hloc, fastperiod=12, slowperiod=26, signalperiod=9)
macdhist_f=[]
iter=0
for x in np.nditer(macdhist):
    iter+=1
    macdhist_f.append([iter,float(x)])
    print(type(x))
print macdhist_f

macdhist_df = pd.DataFrame(macdhist_f)

defaults.width = 450
defaults.height = 350

hist = Histogram(macdhist_df, values='macd hist', bins=50,
                title="MACD Histogram")
show(hplot(hist))
coin = "DASH_"
output_file(coin + "html", title="macd")

用以下命令安装TA-lib,

pip install TA-lib

但得到此错误"命令'gcc'失败,退出状态为1":

检查了故障排除,安装了gcc,python-devel,libffi-devel,openssl-devel,但仍然无法正常工作!

然后使用 conda install -c quantopian ta-lib=0.4.9安装talib但显示错误"以下规格被发现存在冲突: - py-xgboost, - ta-lib 0.4.9*"然后conda info ta-lib, it return the"NoPackagesFoundError: Package missing in current linux-64 channels"

I'm trying to install TA-Lib package in google colab notebook but without success. I tried this guide and also Installing TA-Lib on python x64

I get this error:

我尝试在我的Mac上安装Ta-lib作为全局包时出现gcc错误.

我在下面收到错误:

   gcc -Wno-unused-result -Wsign-compare -Wunreachable-code -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I//anaconda/include -arch x86_64 -I//anaconda/include -arch x86_64 -I//anaconda/lib/python3.6/site-packages/numpy/core/include -I/usr/include -I/usr/local/include -I/opt/include -I/opt/local/include -I//anaconda/include/python3.6m -c talib/common.c -o build/temp.macosx-10.7-x86_64-3.6/talib/common.o

             ^

    error: command 'gcc' failed with exit status 1

我不确定我明白这意味着什么？pip install Ta-lib包丢失了一个文件？它会有意义,但它安装好我的Ubuntu服务器,只是我的Mac有问题.Ubuntu也使用相同版本的Anaconda运行Python.

我的gcc版本如下:

?  ~ which gcc
/usr/bin/gcc
