> Hi,

> https://ci.apache.org/projects/flink/flink-docs-release-1.2/dev/libs/ml/quickstart.html
> When using env.readCsvFile:
> val env = ExecutionEnvironment.getExecutionEnvironment
> val survival = env.readCsvFile[(String, String, String, String)]("path/data")
> I encounter the following error:
> Error:(17, 69) could not find implicit value for evidence parameter of type
> org.apache.flink.api.common.typeinfo.TypeInformation[(String, String, String,
> String)]
> Error occurred in an application involving default arguments.
> val survival = env.readCsvFile[(String, String, String, String)]("path/data")
> ^
> Is it related to this issue ?
