我正在尝试在 Ubuntu 上安装 tensorflow，但收到此消息：

我不知道混合不同型号的所有MC是否可行。我为什么问是因为可读性。我必须始终在终端中打印并将 mc 复制到 Excel 文件中，这确实要求很高，因为我根据所选参数多次运行脚本。
models = {'Model_SVC': model1, 'Model_G_NB': model2, 'Model_LR': model3, 'Model_RF': model4, 'Model_KN': model5, 'Model_MLP': model6}
cv_splitter = KFold(n_splits=10, shuffle=False, random_state=None)
for model_name, model in models.items():
y_pred = cross_val_predict(model, features, ylabels, cv=cv_splitter)
print("Model: {}".format(model_name))
print("Accuracy: {}".format(accuracy_score(ylabels, y_pred)))
cm = confusion_matrix(ylabels, y_pred)
output = pd.DataFrame()
print("matrice confusion: {}".format(cm), file=f)
矩阵如下所示：
Model: Model_SVC
Accuracy: 0.5692307692307692
matrice confusion: [[ 34 4 46]
[ 10 2 33]
[ 16 3 112]]
Model: Model_G_NB
