Hi, I am new to scvi.  
I used jupyterlab and my python version is 3.9.5.  
I installed scvi following the tutorial.  
pip install scvi-tools

I am able to import scvi to my jupyterlab.  
However, when I tried to use it, it reminds me it does not has this attribute or that attribute.  
For example,  
adata = scvi.data.heart\_cell\_atlas\_subsampled() Error: module ‘scvi’ has no attribute ‘data’

scvi.settings.seed = 420 Error: module ‘scvi’ has no attribute ‘settings’

Seems that my scvi contains nothing.

Could anyone give me some help?

Best,  
Huimin Lyu

Can you run `pip show scvi-tools` and paste the output here?

I ran it and the output is:

Do you have a file named scvi.py in the directory where you’re running your notebook? If so, that might be the issue, try deleting or moving that file elsewhere, then re-start your jupyter kernel and `import scvi` again.  
When you type `scvi` at the Python prompt you should get:  
`<module 'scvi' from '<your_path>/lib/python3.7/site-packages/scvi/ __init__.py'>`

Thank you so much. Problem solved.  
I doubt this happened because when I installed scvi-tools the first time, I used the wrong command: pip install scvi  
although I uninstalled scvi later and installed scvi-tools, I was not able to correctly import scvi-tools.  
After I uninstall all scvi, scvi-tools from my global and virtual environment and reinstalled scvi-tools, problem solved.
