python - 将 Pandas 数据框显示到另一个选项卡中

Question

我正在尝试在另一个“输出 View ”选项卡中显示我的 pandas 数据框，如此 iamge 中所示...

https://github.com/quantopian/qgrid/blob/master/docs/images/events_api.gif

我能够使用以下命令安装和试用 qgrid 的基本功能。但无法获得如上所示的确切 View 。

!pip install qgrid
!jupyter nbextension enable --py --sys-prefix qgrid
!jupyter nbextension enable --py --sys-prefix  widgetsnbextension

import qgrid
import pandas as pd
df = pd.read_csv('some.csv')

qgrid_widget = qgrid.show_grid(df, show_toolbar=True)
qgrid_widget

qgrid_widget.get_changed_df()

Answer 1

这些命令应该有效:

预安装:

1. Assume you have conda environment called "myenv"
2. Assume you have jupyter-lab installed in that environment

安装新的Conda环境

source activate myenv
pip install qgrid
jupyter labextension install qgrid
jupyter labextension install @jupyter-widgets/jupyterlab-manager
jupyter nbextension enable --py --sys-prefix qgrid
jupyter nbextension enable --py --sys-prefix widgetsnbextension

加载conda环境

source activate myenv
jupyter-lab
create a notebook under environment myenv

-------------------- 这些只是安装前的程序--------
---------------- 以下是您在 jupyter lab 中使用 qgrid 的方法 ----------

# Lets say you have a pandas dataframe `df`
qgrid_widget = qgrid.show_grid(df.head(), show_toolbar=True)
qgrid_widget
qgrid_widget.get_changed_df()

# right click on this cell
# click Create New View for Output # it will create new tab
# You will see the new window of dataframe

确认

我只是按照新环境的程序进行操作，并且它有效。
