Xgboost算法问题文件为空

Question

我尝试使用 1.7-1 版本的 Xgboost 算法训练数据集。调用 Xgboost 函数时，它会抛出如下错误。

2024-01-19:02:57:27:INFO] Imported framework sagemaker_xgboost_container.training

    raise ReadError("empty file")
tarfile.ReadError: empty file
empty file

我有两个具有相同结构且扩展名为 .csv 的源文件。 我不知道为什么它抱怨 tar 文件为空

此问题已解决。由于入口点 python 代码中存在错误，因此未生成模型输出 (.tar gz)。修正了入口点代码，现在工作正常。
