Unable to upload csv on jupyter

The supported browsers for Jupyter Notebook are Chrome, Safari, FireFox (See).If you are using the other IE or Edge browsers.

Jupyter Notebook is designed to launch the default browser, but your company may not be able to set the default browser as desired.If so, it must be configured in jupyter_notebook_config.py (Windows reference).

If changing your browser doesn't improve, it's not a direct solution, but Jupiter can use shell commands, so you can copy them with shell commands.

# For Linux, Mac:
!cp path_to_csv/*.csv.
# For Windows:
!copy path_to_csv\*.csv.

Also, in Python, it's a little tricky at first to write a routine that copies data, but it can be automated from now on.

 from pathlib import Path
import shutil

files=Path('path_to_csv').glob('*.csv')
For fin files:
    print(f)
    shutil.copy(f, '.')
