colaboratory在安装和导入后不会确认arviz [英] colaboratory will not acknowledge arviz after installation and import

问题描述

在Google的实验室中，已安装的arviz然后确实导入了arviz，而没有错误，但是在代码单元中，pm.plot_posterior(samples)出现了错误:未安装arviz.

In Google's colaboratory, installed arviz then did import arviz without error, but in a code cell, pm.plot_posterior(samples) gets error: arviz not installed.

推荐答案

在导入PyMC3之前安装Arviz ，否则显然找不到它.就您而言，只需重新启动运行时(运行时> 重新启动运行时... )即可使其正常运行.

Install Arviz prior to importing PyMC3, otherwise it apparently cannot find it. In your case, simply restarting the runtime (Runtime > Restart runtime...) should get it working.
