Expected 2D array, got 1D array instead:

[Gustavo Capato]

Boa tarde estou utilizando o código fonte que baixei na plataforma e utilizando o código puro no spyder sem alterações, estou recebendo este erro quando executo a parte final.

 

Erro completo abaixo:

 

 

funcao_previsao = make_input_fn(novas_casas, num_epochs = 1, shuffle = False)
previsoes = regressor.predict(input_fn = funcao_previsao)
previsoes
list(previsoes)

for p in regressor.predict(input_fn = funcao_previsao):
print(scaler_y.inverse_transform(p[‘predictions’]))

Reshape your data either using array.reshape(-1, 1) if your data has a single feature or array.reshape(1, -1) if it contains a single sample.

Tente alterar a última linha para:

print(scaler_y.inverse_transform(p[‘predictions’].reshape(1, -1))
