The Google Cloud Storage location for a csv file which preserves a list of ImportProductSetRequests in each line.
The Google Cloud Storage URI of the input csv file. The URI must start with ``gs://``. The format of the input csv file should be one image per line. In each line, there are 8 columns. 1. image-uri 2. image-id 3. product-set-id 4. product-id 5. product-category 6. product-display-name 7. labels 8. bounding-poly The ``image-uri``, ``product-set-id``, ``product-id``, and ``product-category`` columns are required. All other columns are optional. If the ``ProductSet`` or ``Product`` specified by the ``product-set-id`` and ``product-id`` values does not exist, then the system will create a new ``ProductSet`` or ``Product`` for the image. In this case, the ``product-display-name`` column refers to display_name, the ``product-category`` column refers to product_category, and the ``labels`` column refers to product_labels. The ``image-id`` column is optional but must be unique if provided. If it is empty, the system will automatically assign a unique id to the image. The ``product-display-name`` column is optional. If it is empty, the system sets the display_name field for the product to a space (" "). You can update the ``display_name`` later by using the API. If a ``Product`` with the specified ``product-id`` already exists, then the system ignores the ``product-display-name``, ``product-category``, and ``labels`` columns. The ``labels`` column (optional) is a line containing a list of comma-separated key-value pairs, in the following format: :: "key_1=value_1,key_2=value_2,...,key_n=value_n" The ``bounding-poly`` column (optional) identifies one region of interest from the image in the same manner as ``CreateReferenceImage``. If you do not specify the ``bounding-poly`` column, then the system will try to detect regions of interest automatically. At most one ``bounding-poly`` column is allowed per line. If the image contains multiple regions of interest, add a line to the CSV file that includes the same product information, and the ``bounding-poly`` values for each region of interest. The ``bounding-poly`` column must contain an even number of comma-separated numbers, in the format "p1_x,p1_y,p2_x,p2_y,...,pn_x,pn_y". Use non-negative integers for absolute bounding polygons, and float values in [0, 1] for normalized bounding polygons. The system will resize the image if the image resolution is too large to process (larger than 20MP).
