在 Power BI 中使用 Python 脚本，导入错误：缺少所需的依赖项 ['numpy']

Question

我是个新手Power BI，我尝试在其中设置 python 脚本。我已经更改了选项并激活了Python scripting. 之后我收到错误：

DataSource.Error: ADO.NET: Python script error.
Traceback (most recent call last):
  File "PythonScriptWrapper.PY", line 2, in <module>
    import os, pandas, matplotlib.pyplot
  File "C:\Users\mm\AppData\Local\Continuum\anaconda3\lib\site-packages\pandas\__init__.py", line 19, in <module>
    "Missing required dependencies {0}".format(missing_dependencies))
ImportError: Missing required dependencies ['numpy']

Details:
    DataSourceKind=Python

我检查了conda列表，它包含numpy.

我已经安装numpy并pandas再次收到以下消息

C:\Users\mm\AppData\Local\Continuum\anaconda3>py -m pip install numpy
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Requirement already satisfied: numpy in c:\users\mm\appdata\local\continuum\anaconda3\lib\site-packages (1.15.4)

C:\Users\mm\AppData\Local\Continuum\anaconda3>py -m pip install pandas

正如你所看到的，我正在使用 anaconda3，但我的机器上安装了另一个 Python。我尝试了很多方法但没有任何帮助

Answer 1

打开Anaconda Prompt：然后，您必须转到要在PowerBI中使用的Conda环境。我有一个环境“temp”，所以我首先在“Anaconda Prompt”中激活它：

(base) C:\Users\ashish>conda activate temp

然后我进入安装文件夹中包含“PowerBI”可执行文件的目录：

(temp) C:\Users\ashish>cd "C:\Program Files\Microsoft Power BI Desktop\bin"

然后，我从提示符启动 PowerBI：

(temp) C:\Program Files\Microsoft Power BI Desktop\bin>PBIDesktop.exe

这修复了您收到的 NumPy 错误。如果您希望任何其他包与 PowerBI 一起使用，请在相应的“Conda 环境”中安装该包（在我的例子中是“temp”）。
