How to Remove IndentationError: expected an indented block: except ValueError: in Google Colab
问题
在给定的数据集上，我被要求对数据集执行 5 个机器学习模型。
以下是我的代码：
standard_scaler = StandardScaler()
try:
X_train=standard_scaler.fit_transform(X_train)
X_test=standard_scaler.fit_transform(X_test)
except ValueError:
但是我一直在得到以下错误：
except ValueError:
^
IndentationError: expected an indented block
有人能帮助我解决这个问题吗？

except ValueError:
I keep getting

Can someone please help me figure out this issue?

你需要在 ValueError 中添加一个代码块：
standard_scaler = StandardScaler()
try:
X_train = standard_scaler.fit_transform(X_train)
X_test = standard_scaler.fit_transform(X_test)
except ValueError:
pass # 或者其他你需要的值
英文:
You need a block in ValueError:
standard_scaler = StandardScaler()
try:
X_train=standard_scaler.fit_transform(X_train)
X_test=standard_scaler.fit_transform(X_test)
except ValueError:
pass #or any other value you need
