Check, uncheckbox error

🎈 Using Streamlit
1

Dear awesome-streamlit users!

I’m using file_uploader to upload a csv file, I converted the bytesIO file to a dataframe and created a checkbox to show the first 5 lines in my dataframe.
No issues no upload file or when I check the checkbox for the first time, otherwise when I uncheck the box and re-check the box I got the following error:

EmptyDataError: No columns to parse from file

Traceback:

```

    self._reader = parsers.TextReader(src, **kwds)File "pandas/_libs/parsers.pyx", line 545, in pandas._libs.parsers.TextReader.__cinit__
```

Does anybody know how to solve it?

In addition, once I upload the csv file is it possible to run more than 1 function with it?
