Hi @Jonatas_Liasch, and welcome to the Losant Forums.
First, thanks for including your Jupyter file. What you provided validates against the nbformat v4.5 schema; however, the version of Jupyter we are running requires your notebook to validate against nbformat v4.2.
I am putting in a request with our engineering team right now to add a notebook image that supports your version. In the meantime, if you are able to re-compile your notebook to validate against the v4.2 schema, then you should be able to upload.
One other thing to note - if you do manage to re-compile and upload this notebook, your reference to a file on your local system will fail:
"arquivo = pd.read_csv('C:/Users/Usuario/Downloads/wine_dataset.csv')"
Instead, you will need to include your CSV as a notebook input and change your code to reference it accordingly.
