1 terminal

Terminal opening process: file browser (Ctrl + Shift + F) - new startup page (Ctrl + Shift + L) - terminal

terminal

The terminal does not have sudo privileges;
You can only open up to 5 terminals at the same time;
Both python and pip environment variables have been configured;

6 Package Management

6.1 Persistent installation of third-party packages for Python

If you need to perform persistent installation, you need to use the persistent path installation, for example:

!mkdir /home/aistudio/external-libraries
!pip install paddlenlp -t /home/aistudio/external-libraries

At the same time, the following code needs to be run every time the environment starts:

import sys 
sys.path.append('/home/aistudio/external-libraries')

6.2 Configure matplotlib to display Chinese

matplotlibThe default font used does not support displaying Chinese, which can be adjusted as follows:

import matplotlib

matplotlib.rcParams["font.sans-serif"] = ["FZSongYi-Z13S"] # 指定支持中文的默认字体
matplotlib.rcParams["axes.unicode_minus"] = False # 解决保存图像是负号'-'显示为方块的问题
