<pre>
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 6 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

Columns 1, 3, 4, and 5 are required, other columns are optional. A new
ProductSet/Product with the same id will be created on the fly
if the ProductSet/Product specified by product_set_id/product_id does not
exist.

The image_id field is optional but has to be unique if provided. If it is
empty, we will automatically assign an unique id to the image.

The product_display_name field is optional. If it is empty, a space (" ")
is used as the place holder for the product display_name, which can
be updated later through the realtime API.

If the Product with product_id already exists, the fields
product_display_name, product_category and labels are ignored.

If a Product doesn't exist and needs to be created on the fly, the
product_display_name field refers to
[Product.display_name][google.cloud.vision.v1p3beta1.Product.display_name],
the product_category field refers to
[Product.product_category][google.cloud.vision.v1p3beta1.Product.product_category],
and the labels field refers to [Product.labels][].

Labels (optional) should be a line containing a list of comma-separated
key-value pairs, with the format
    "key_1=value_1,key_2=value_2,...,key_n=value_n".

The bounding_poly (optional) field is used to identify one region of
interest from the image in the same manner as CreateReferenceImage. If no
bounding_poly is specified, the system will try to detect regions of
interest automatically.

Note that the pipeline will resize the image if the image resolution is too
large to process (above 20MP).

Also note that at most one bounding_poly is allowed per line. If the image
contains multiple regions of interest, the csv should contain one line per
region of interest.

The bounding_poly column should contain an even number of comma-separated
numbers, with the format "p1_x,p1_y,p2_x,p2_y,...,pn_x,pn_y". Nonnegative
integers should be used for absolute bounding polygons, and float values
in [0, 1] should be used for normalized bounding polygons.
