我创建了一个虚拟环境并安装了Jupyter notebood和jupyter实验室
导入大熊猫后，我得到 ModuleNotFoundError: No module named 'pandas'
对jupyter notebook执行相同的操作不会给我一个错误，该错误在同一venv中运行
我将熊猫安装到venv中，但出现了相同的错误
导入本地python模块工作正常
将!pip install pandas插入上方的空白单元格中
Requirement already satisfied: pandas in /home/curwin/jupyterlab/venv/lib/python3.8/site-packages (1.1.3)
Requirement already satisfied: pytz>=2017.2 in /home/curwin/jupyterlab/venv/lib/python3.8/site-packages (from pandas) (2020.1)

Requirement already satisfied: numpy>=1.15.4 in /home/curwin/jupyterlab/venv/lib/python3.8/site-packages (from pandas) (1.19.2)
Requirement already satisfied: six>=1.5 in /home/curwin/jupyterlab/venv/lib/python3.8/site-packages (from python-dateutil>=2.7.3->pandas) (1.14.0)
答案 0 :(得分：0)
我已经在venv中安装了一个内核
ipython kernel install --user --name=.venv
并从该内核运行笔记本即可解决问题
