If you don’t have any data of your own to work with, you can find some example datasets at http://data.h2o.ai.
There are multiple ways to import data in H2O flow:
Click the Assist Me! button in the row of buttons below the menus, then click the importFiles link. Enter the file path in the auto-completing Search entry field and press Enter. Select the file from the search results and confirm it by clicking the Add All link.
In a blank cell, select the CS format, then enter importFiles ["path/filename.format"] (where path/filename.format represents the complete file path to the file, including the full file name. The file path can be a local file path or a website address.
Note: For S3 file locations, use the format importFiles [ "s3n:/path/to/bucket/file/file.tab.gz" ]
- For an example of how to import a single file or a directory in R, refer to the following example.
After selecting the file to import, the file path displays in the “Search Results” section. To import a single file, click the plus sign next to the file. To import all files in the search results, click the Add all link. The files selected for import display in the “Selected Files” section.
Note: If the file is compressed, it will only be read using a single thread. For best performance, we recommend uncompressing the file before importing, as this will allow use of the faster multithreaded distributed parallel reader during import. Please note that .zip files containing multiple files are not currently supported.
To import the selected file(s), click the Import button.
To remove all files from the “Selected Files” list, click the Clear All link.
To remove a specific file, click the X next to the file path.
After you click the Import button, the raw code for the current job displays. A summary displays the results of the file import, including the number of imported files and their Network File System (nfs) locations.
