Upload Button/ Action

[uzimando]

Is there an upload component? If not what about an action component or something similar that I can use to to make my own button?

There is not an upload component yet. There will be one in the future. The only alternative now would be to create your own button component using React and the dash plugin system (https://plot.ly/dash/plugins) or to contract out the advanced development team to build one.

I followed the instruction on the building your own compoents section but I run into when i import acme_components:

IOError: [Errno 2] No such file or directory: ‘/usr/lib/python2.7/site-packages/acme_components-0.0.1-py2.7.egg/acme_components/metadata.json’

It looks like the file in in the .gitignore, how do i get around this?

This is awesome! How can i read .csv with utf-8 encoding? i have to try dff = pd.read_csv(io.StringIO(content),sep=’,’,encoding=‘utf-8’) , but

@roman

read_csv

I think it shoud be ‘utf_8’ instead of ‘utf-8’: check codecs — Codec registry and base classes — Python 3.12.1 documentation

[roman]

same result =( i tried some other encodings from https://docs.python.org/3/library/codecs.html#standard-encodings with negative result
