pandas - 我错过了什么？sklearn 适合模块

Question

我认为机器学习的输入不能是 .fit 中的文本我应该使用什么或者我应该如何更改我的代码？这个ai应该用年月和日进行训练，它应该作为输出作物（第一，第二，第三）（我不知道要添加什么更多细节，但我需要发布更多细节，所以我只是在时刻。代码：

import pandas as pd
from sklearn.tree import DecisionTreeClassifier
from sklearn.model_selection import train_test_split
from sklearn.metrics import accuracy_score

event_data = pd.read_excel("Jacob's Farming Contest.xlsx")
event_data.fillna(0, inplace=True)
X = event_data.drop(columns=['First Crop', 'Second Crop', 'Third Crop'])
y = event_data.drop(columns=['Year', 'Month', 'Day'])
X_train, x_test, y_train, y_test = train_test_split(X, y, test_size=0.2)

model = DecisionTreeClassifier()
model.fit(X_train, y_train)
# predictions = model.predict(X_test)

错误：
