如何在anaconda上更换python版本

1.anaconda上装的是python3.7。power bi现在还不支持python3.7。如果在power bi里更改ananconda做ide，则会报如下错误。需要降低anaconda中python的版本。
DataSource.Error: ADO.NET: Python script error.
Traceback (most recent call last):
File “PythonScriptWrapper.PY”, line 2, in
import os, pandas, matplotlib.pyplot
File “C:\Users\mm\AppData\Local\Continuum\anaconda3\lib\site-packages\pandas_init_.py”, line 19, in
“Missing required dependencies {0}”.format(missing_dependencies))
ImportError: Missing required dependencies [‘numpy’]
