dear [lahsaouinouhaila](https://forum.anaconda.com/u/lahsaouinouhaila).

Thank you for posting.

Since you presented the detailed error code and source code, it was easy to understand the cause.  
For details, please refer to the following URL, but it can be easily corrected.

dear [lahsaouinouhaila](https://forum.anaconda.com/u/lahsaouinouhaila).

thank you for reply.

In pyscript, Pandas often doesn’t work because the numpy, pytz, and dateutil needed to run Pandas are often not imported.

I think this is because the current pyscript specification requires you to specify the required packages directly.

In other words, libraries that are located directly in the /lib/python3.9 directory instead of site-packages will be imported without doing anything, but in the case of other libraries, if they are not directly located. I don’t think it has been imported.

Especially in the case of numpy and scipy, not only python scripts but also libraries such as dll and lib.so are used.

In other words, pyscript is not a runtime engine, but an interface for launching Python on the base system.

If you have any requests for improvement in the future, we would appreciate it if you could contact us.

Regards, you.

Thank you sir for replying I appreciate it .  
I wonder if I can use some thing else that can play the same role as pandas using pyscript

dear [lahsaouinouhaila](https://forum.anaconda.com/u/lahsaouinouhaila).

thank you for reply.  
I have a few options, each with its pros and cons.

For details, please refer to the article at the following URL.

> Stop using Pandas

In terms of using numpy, GPU, SQL, etc., they may not be compatible with Pyscript.
