NYC Citibike Demand with Weather (Large)的笔记本电脑演示由于访问Citibike数据集的错误而无法在本地运行。当运行以下单元格时：
big_test = [mylocate("bigdata/laptop/citibike-nyc/2013-07.csv"),
mylocate("bigdata/laptop/citibike-nyc/2013-08.csv"),
mylocate("bigdata/laptop/citibike-nyc/2013-09.csv"),

print("Import and Parse bike data")
data = h2o.import_file(path=big_test)
如果data_source_is_s3设置为true，则会输出以下错误：
H2OResponseError: Server error java.lang.IllegalArgumentException:
