Pycharm报错Estimator fit failed. The score on this train-test该怎么解决

代码如下：

from sklearn.datasets import load_breast_cancer
from sklearn.ensemble import RandomForestClassifier
from sklearn.model_selection import GridSearchCV
from sklearn.model_selection import cross_val_score
import matplotlib.pyplot as plt
# noinspection PyUnresolvedReferences
import pandas as pd
import numpy as np

data = load_breast_cancer()

scorel = []
for i in range(0, 200, 10):
    rfc = RandomForestClassifier(n_estimators=i + 1,
                                 n_jobs=-1,
                                 random_state=90)
    score = cross_val_score(rfc, data.data, data.target, cv=10).mean()  # 交叉验证
    scorel.append(score) 

print(max(scorel), (scorel.index(max(scorel)) * 10) + 1)

plt.figure(figsize=[20, 5])
plt.plot(range(1, 201, 10), scorel)
plt.show()
