c# - 尝试在 C# 中运行 IronPython：“LightException”对象没有属性“qstkutil”

Question

我正在尝试在 VS c# 中运行此代码：

    //calls script that will be executed as a new Thread
    private void portfolioAnalysisToolStripMenuItem_Click(object sender, EventArgs e)
    {
        Thread myThread = new Thread(new ThreadStart(StartPy));
        myThread.Start();

    }

    //directory and script
    public static void StartPy()
    {

        string filename = "\\Scripts\\HM1.py";
        string path = Assembly.GetExecutingAssembly().Location;
        string rootDir = Directory.GetParent(path).FullName;

        RunPythonFile(rootDir, filename);
    }


    public static double RunPythonFile(string rootDir, string filename)
    {

        ScriptEngine engine = Python.CreateEngine();


        ScriptScope scope = engine.CreateScope();

        ICollection<string> paths = engine.GetSearchPaths();
        string dir = @"C:\Python27\Lib";
        paths.Add(dir);
        string dir2 = @"C:\Python27\Lib\site-packages";
        paths.Add(dir2);
        string dir3 = @"C:\Python27\Dlls";
        paths.Add(dir3);
        engine.SetSearchPaths(paths);

        ScriptSource source;
        source = engine.CreateScriptSourceFromFile(rootDir + filename);

        double result = source.Execute(scope);
        return result;
    }

错误显示在以下行中：“double result = source.Execute(scope);” 它说：“LightException”对象没有属性“qstkutil”

蟒蛇代码是：

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import QSTK.qstkutil.qsdateutil as du
import QSTK.qstkutil.tsutil as tsu
import QSTK.qstkutil.DataAccess as da

import datetime as dt
import matplotlib.pyplot as plt
import pandas as pd
import numpy as np
import itertools

def main():
    ''' Main Function'''


ls_symbols = ["AAPL", "GLD", "GOOG","XOM"]
dt_start = dt.datetime(2011, 1, 1)
dt_end = dt.datetime(2011, 12, 31)
dt_timeofday = dt.timedelta(hours=16)
ldt_timestamps = du.getNYSEdays(dt_start, dt_end, dt_timeofday)


c_dataobj = da.DataAccess('Yahoo')
ls_keys = ['open', 'high', 'low', 'close', 'volume', 'actual_close']
ldf_data = c_dataobj.get_data(ldt_timestamps, ls_symbols, ls_keys)
d_data = dict(zip(ls_keys, ldf_data))


na_price = d_data['close'].values


na_normalized_price = na_price / na_price[0, :]

cumm_ret = na_normalized_price.copy()
allo=np.arange(0,1.1,0.1)
valid_allocations=[[float('%.1f'%a),float('%.1f'%b),float('%.1f'%c),float('%.1f'%d)] for a in allo for b in allo for c in allo for d in allo if a+b+c+d==1]

sharpe = 0
max_a = 0
avg = 0
std = 0
best_sharpe = 0.0
best_alloc = 0

for i in range(0,len(valid_allocations)-1):

    ls_alloc = valid_allocations[i]

    fund_inv = cumm_ret * ls_alloc

    tot_fund_inv = np.sum(fund_inv,axis=1)

    daily_ret = tsu.returnize0(tot_fund_inv)

    avg_daily_ret = np.average(daily_ret)

    std_dev = np.std(daily_ret)

    sharpe_ratio = np.sqrt(252) * (avg_daily_ret/std_dev)

    if sharpe_ratio > best_sharpe:

        best_sharpe = sharpe_ratio
        best_alloc = ls_alloc

print best_sharpe, best_alloc


if __name__ == '__main__':
    main()

提前感谢您的帮助！！

使用 ipy.exe -X:ExceptionDetail -X:ShowClrExceptions 运行它，堆栈跟踪为：

  AttributeError: 'LightException' object has no attribute 'qstkutil'
  CLR Exception:
    MissingMemberException
  :

所以...通过使用 -X:Debug 运行，首先当我调用 IronPython 时，出现了以下内容：

   Error processing line 1 of C:\Program Files (x86)\IronPython 2.7\lib\site-packag
es\QSTK-0.2.6-py2.7-nspkg.pth:

并运行程序：
