السلام عليكم لقد قمت بنثبيت lightGBMو لكن عند استعماله يظهر خطأ انه غير مثبت مع العلم ان استعمل pycharmو windows 7 و python 3.7وشكرا

ما هو الفرق بين M 5Tree,Decision Tree; M Tree

Node: 'sequential/lstm/TensorArrayUnstack/TensorListFromTensor' Specified a list with shape [1,1] from a tensor with shape [32,1] [[{{node sequential/lstm/TensorArrayUnstack/TensorListFromTensor}}]] [Op:__inference_train_function_1584] LSTM3.py

لدي الكود التالي : data = pd.read_excel('testreglogistic.xlsx',sheet_name='raz1') x=data.loc[:,data.columns != 'g'].values y=data.loc[:,'g'].values x_train, x_test, y_train, y_test= train_test_split(x,y, test_size= 0.25, random_state=42) sc= StandardScaler() x_train= sc.fit_transform(x_train) x_test= sc.transform(x_test) y_train = preprocessing.normalize([y_train]) y_test = preprocessing.normalize([y_test]) model= RandomForestRegressor(n_estimators=20,max_depth=3, random_state=42) model.fit(x_train,y_train) y_pred=model.predict(x_test) يظهر الخطأ التالي : ValueError: Found input variables with inconsistent numbers of samples: [273, 1]
