运行 BigDL 文本分类器失败

Question

当我使用单节点 PySpark 运行 BigDL (https://bigdl-project.github.io/0.4.0/) Text Classifier example (https://github.com/intel-analytics/BigDL/tree/master/pyspark/bigdl/models/textclassifier) 时，出现以下错误。有什么解决办法吗？

配置：

Java:

openjdk version "1.8.0_141"
OpenJDK Runtime Environment (build 1.8.0_141-8u141-b15-1~deb9u1-b15)
OpenJDK 64-Bit Server VM (build 25.141-b15, mixed mode)

PySpark:

dk@dk:~$ pyspark

Answer 1

python 脚本试图在 /usr/local/lib/python3.5/dist-packages/bigdl/bigdl.log 中创建一个 bigdl.log 文件，该文件是 linux 中的受保护目录，只能通过 root-access 访问。

您可以指定 redire_spark_logs 函数的日志文件路径，例如 redire_spark_logs(log_path='/home/bigdl-projects')。查看 here 了解更多详情。
