我们有一个非常大的 CSV 文件，已作为 dask 数据框导入。我举一个小例子来解释这个问题。

import dask.dataframe as dd
df = dd.read_csv("name and path of the file.csv")
df.head()

输出

col1 | col2 | col3 | col4 
22   | Nan  | 23   |  56
12   |  54  | 22   |  36
48   | Nan  | 2    |  45
76   | 32   | 13   |  6
23   | Nan  | 43   |  8
67   | 54   | 56   |  64
16   | 32   | 32   |  6
3    | 54   | 64 …

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.
