Python - 使用 Anaconda 的 ModuleNotFound 错误

Question

我正在尝试运行这个程序：

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

from __future__ import absolute_import
from __future__ import division
from __future__ import print_function
from __future__ import unicode_literals
from io import open

from multiprocessing import Pool
import buildingspy.simulate.Simulator as si


# Function to set common parameters and to run the simulation
def simulateCase(s):
''' Set common parameters and run a simulation.

:param s: A simulator object.

'''
s.setStopTime(86400)
# Kill the process if it does not finish in 1 minute
s.setTimeOut(60)
s.showProgressBar(False)
s.printModelAndTime()
s.simulate()


def main():
''' Main method that configures and runs all simulations
'''
import shutil
# Build list of cases to run
li = []
# First model
model = 'Buildings.Controls.Continuous.Examples.PIDHysteresis'
s = si.Simulator(model, 'dymola', 'case1')
s.addParameters({'con.eOn': 0.1})
li.append(s)
# second model
s = si.Simulator(model, 'dymola', 'case2')
s.addParameters({'con.eOn': 1})
li.append(s)

# Run all cases in parallel
po = Pool()
po.map(simulateCase, li)

# Clean up
shutil.rmtree('case1')
shutil.rmtree('case2')

# Main function
if __name__ == '__main__':
main()

我不断收到此错误：

File "C:/Users/Toshiba/.spyder-py3/temp.py", line 11, in <module>
    import buildingspy.simulate.Simulator as si

ModuleNotFoundError: No module named 'buildingspy'

我已经多次使用 pip 安装了该软件包，并且没有任何变化。

我错过了什么？

This是这段代码的来源。

该错误可能是由于您的计算机上安装了多个 python：
https://docs.python.org/3/installing/#work-with-multiple-versions-of-python-installed-in-parallel

请在您的脚本（或新脚本）的某处添加以下行并从 Spyder 运行一次，然后从控制台运行一次并比较输出：

import sys
print("python: {}".format(sys.version))
# also add the following if running from python 3
from shutil import which
print(which("python"))

Buildingspy 必须使用 pip 安装，我建议使用命令安装它：

python -m pip install -U https://github.com/lbl-srg/BuildingsPy/archive/master.zip

Anaconda 在开始菜单中添加了一个Anaconda prompt，用它来确保 python.exe 的路径是正确的。

一旦正确安装 BuildingsPy，您将遇到在 Windows 上多处理无法从 Spyder（或 IPython/Jupyter）工作的问题，请同时阅读此问题：

您必须从命令行运行脚本。
