Question Answering (Generative Models)

Parameters

• use local model Indicates if a local model should be used based on a local file directory or if a model should be used from the Huggingface portal. If a local model is to be used, all task operators require a file object referencing to the model directory as a second input. If this parameter is unchecked, you will need to specify the full model name coming from the Huggingface portal for the “model” parameter.
• model The model from the Huggingface portal which will be used by the operator. Only used when the “use local model” parameter is unchecked. The model name needs to be the full model name as found on each model card on the Huggingface portal. Please be aware that using large models can result in downloads of many gigabytes of data and models will be stored in a local cache.
• name The name of the new column which will be created as a result.
• question This column needs to contain the questions.
• context This column needs to contain the context about which the questions are asked.
• top k Defines how many solutions are created by the model. If more than one solution is created, then multiple result columns will be created as well.
• allow impossible Indicates if impossible or an empty answer is allowed as a result.
• max question tokens The maximum number of tokens produced as input by the model. Note that some models can only work with specific maximum numbers of tokens. Please refer to the model documentation pages on Huggingface for more information about such limits.
• max target tokens The maximum number of tokens produced as output by the model. Note that some models can only work with specific maximum numbers of tokens. Please refer to the model documentation pages on Huggingface for more information about such limits.
• device Where the finetuning should take place. Either on a GPU, a CPU, or Apple’s MPS architecture. If set to Automatic, the training will prefer the GPU if available and will fall back to CPU otherwise.
• device indices If you have multiple GPUs and computation is set up to happen on GPUs you can specify which ones are used with this parameter. Counting of devices starts with 0. The default of “0” means that the first GPU device in the system will be used, a value of “1” would refer to the second and so on. You can utilize multiple GPUs by providing a comma-separated list of device indices. For example, you could use “0,1,2,3” on a machine with four GPUs if all four should be utilized. Please note that RapidMiner performs data-parallel computation which means that the model needs to be small enough to be completely loaded on each of your GPUs.
• data type Specifies the data type under which the model should be loaded. Using lower precisions can reduce memory usage while leading to slightly less accurate results in some cases. If set to “auto” the data precision is derived from the model itself.
• revision The specific model version to use. The default is “main”. The value can be a branch name, a tag name, or a commit id of the model in the Huggingface git repository.
• trust remote code Whether or not to allow for custom code defined on the Hub in their own modeling, configuration, tokenization or even pipeline files.
• conda environment The conda environment used for this model task. Additional packages may be installed into this environment, please refer to the extension documentation for additional details on this and on version requirements.
