如何使用 JMP18 Python 脚本执行机器学习建模？你好，
我正在使用 JMP Python 脚本（JMP18）创建 LightGBM 模型。
我当前的设置如下：
- X 变量：“train1.csv”文件，D1 至 D1776 列
- Y 变量：“y1.csv”文件，“活动”列
- 预测目标“活动”：“test1.csv”文件，D1至D1776列
- 注意：原始文件“train_original.csv”文件，列活动到 D1776。来自 Kaggle.com（ 预测生物反应）
如果有人能针对以下问题提供指导，我将不胜感激：
- 无法在 JMP18 Python 环境中执行 LightGBM 建模
我在下面附上了我的 JMP Python 脚本供您参考。详情请参阅以下内容。
提前感谢您的时间！:)

train1.head() # No Result in JMP, but it's okay. It's fine to open the datatable using 'jmp.open'
y1.head() # No Result in JMP, but it's okay. It's fine to open the datatable using 'jmp.open'
# train1 = jmp.open('D:/steve.kim/Kaggle/BI Biological Response/train1.csv')
# y1 = jmp.open('D:/steve.kim/Kaggle/BI Biological Response/y1.csv')
# 01 Modeling training - Library import
from lightgbm import LGBMClassifier
# 02 Modeling training - LGBM Baseline model without hyperparameter tuning
lgb = LGBMClassifier()
# 03 Modeling training - define X (factors) and Y (responses) variables
lgb.fit(train1, y1) # lightgbm.basic.LightGBMError: Length of labels differs from the length of #data
# 04 Predict
predslgb = lgb.predict_proba(test1)

抱歉，这个问题！
python pandas 和 lightGBM 在 JMP18 python 脚本中运行良好！: )

print(mean_squared_error(test_answer, sub_lgb))回复：如何使用 JMP18 Python 脚本执行机器学习建模 (LGBM)？哦...当我将其视为终端环境而不是 jupyter 笔记本后，代码‘head()’运行良好！
y1 = pd.read_csv('D:/steve.kim/Kaggle/BI Biological Response/y1.csv')
print(y1.head()) 然后我就可以从嵌入的日志中获取代码结果！
所以我认为我也能解决其余的事情。
