erro no k_means:’NoneType’ object has no attribute ‘split’

[Andre Luiz]

Boa tarde!! Tá dando erro . Pode me ajudar,por favor?

pip install –upgrade scikit-learn threadpoolctl numpy

kmeans_cartao = KMeans(n_clusters=i, random_state=0)
kmeans_cartao.fit(x_cartao)
wcss.append(kmeans_cartao.inertia_)

Olá André,

Executei o código do Colab disponibilizado no curso e não tive nenhum erro.

De nossa experiência, nesses casos geralmente o aluno esqueceu de rodar alguma célula anterior, ou modificou o código. Também é possível que você tenha tentado ler a base de dados no ambiente Python antes que o upload finalizasse.

Para o primeiro caso, te recomendo fazer uma cópia nova do notebook da aula e rodar desde o início. Para o segundo, verifique que a “rodinha” que aparece durante o upload sumiu antes de carregar os dados no ambiente Python.
