python：可以从命令行导入包，但不能从 jupyter notebook

Question

I've gotten a problem where I'm trying to import the tabula package into jupyter notebooks. I activated my conda virtual environment, pip installed tabula-py, and ran pip freeze . It confirmed that tabula-py was installed.

certifi==2021.5.30
distro==1.6.0
et-xmlfile==1.1.0
greenlet==1.1.0
importlib-metadata==4.6.1
keyring==23.0.1
numpy==1.21.1
openpyxl==3.0.7
pandas==1.3.0
pyodbc==4.0.31
python-dateutil==2.8.2
pytz==2021.1
pywin32-ctypes==0.2.0
six==1.16.0
SQLAlchemy==1.4.21
tabula-py==2.3.0
wincertstore==0.2
XlsxWriter==1.4.4
zipp==3.5.0

While my virtual environment was active, I tested out importing the tabula package from the command line ( import tabula ). Everything works! I run exit() to get out of the python instance, then run jupyter notebook to bring up a jupyter notebook. (still in my virtual environment)

However, in jupyter my import statement no longer works, even though i didn't change anything. I run help('modules') within jupyter, and now tabula doesn't exist in my list of packages???? I'm not sure why it isn't working. I have the Java PATH set, and it works fine everywhere except jupyter notebook.

Try run this command:

!pip install tabula

After this try to import it and see if it works
