How do we remove the counter widget in fileupload in ipywidgets?
Quoting user kebwi here from FileUpload displayed counter should be optional · Issue #2904 · jupyter-widgets/ipywidgets · GitHub
Not all users necessarily want the FileUpload button to display the upload-count in parentheses. Some applications and interface designs/layouts may require fine-grained control of the look of the interface and could find the counter extraneous or simply “busying”. I have found no way to get rid of it.
