/language/datasets | The name parameter was passed in, but no value was provided. | | 400 | Bad Request | Uploading a dataset requires either the data field. | POST
/language/datasets/upload | The path to the local .zip file or the URL to the .zip file in the cloud wasn’t specified. | | 400 | Bad Request | The data parameter cannot be duplicated | POST
/language/datasets/upload | The data parameter cannot be duplicated | | 400 | Bad Request | The dataset is not yet available for update, try again once the dataset is ready. | PUT
/language/datasets/<DATASET_ID>/upload | You’re adding examples to a dataset that’s currently being created. You must wait for dataset to become available before you can add examples to it. | | 400 | Bad Request | Failed to download the dataset from the public URL. | POST
/language/datasets/upload/
language/datasets/upload/sync | The API can't access the dataset file via the URL provided.
When specifying the URL for a .zip file in a cloud drive service like Dropbox, be sure it's a link to the file and not a link to the interactive download page. For example, the URL should look like https://www.dropbox.com/s/abcdxyz/mountainvsbeach.zip?dl=1. | | 400 | Bad Request | Supported dataset types: [image, image-detection, image-multi-label] | POST
/language/datasets/upload | The type request parameter contains a value that isn't a valid dataset type. | | 400 | Bad Request | Example max size supported is 1024000. | POST
/language/datasets/<DATASET_ID>/examples | The image file being added as an example exceeds the maximum file size of 1 MB. | | 404 | Not Found | None | Any dataset, label, or example resources. | The requested REST resource doesn’t exist or you don't have permission to access the resource. | | 404 | Not Found | Unable to find dataset. | GET
/language/datasets/<DATASET_ID> |

400	Bad Request	Invalid id `<MODEL_ID>`	GET `/language/train/<MODEL_ID>/lc`	There’s no model with an ID that matches the `modelId` parameter.
400	Bad Request	The job has not terminated yet; its current status is RUNNING. The job has not terminated yet; its current status is QUEUED.	GET `/language/models/<MODEL_ID>`	The model for which you are getting metrics hasn’t completed training.
