# Pipeline Steps

Konduit-Serving provides various types of steps included in Pipeline from pre-processing, serving Machine Learning or Deep Learning model and post-processing. This section offers all the configurations with descriptions that may help set your Pipeline Steps. The example of `PipelineSteps`: 

```
inferenceConfiguration.pipeline(SequencePipeline.builder()
                .add(new ImageToNDArrayStep() //add ImageToNDArrayStep() into pipeline to set image to NDArray for input
                        .config(new ImageToNDArrayConfig() //image configuration
                                .width(28)
                                .height(28)
                                .dataType(NDArrayType.FLOAT)
                                .aspectRatioHandling(AspectRatioHandling.CENTER_CROP)
                                .includeMinibatchDim(true)
                                .channelLayout(NDChannelLayout.GRAYSCALE)
                                .format(NDFormat.CHANNELS_FIRST)
                                .normalization(ImageNormalization.builder().type(ImageNormalization.Type.SCALE).build())
                        )
                        .keys("image")
                        .outputNames("input_layer")
                        .keepOtherValues(true)
                        .metadata(false)
                        .metadataKey(ImageToNDArrayStep.DEFAULT_METADATA_KEY))
                .add(new Nd4jTensorFlowStep() //add Nd4jTensorFlowStep into pipeline
                        .modelUri(modelTrainResult.modelPath())
                        .inputNames(modelTrainResult.inputNames())
                        .outputNames(modelTrainResult.outputNames())
                ).add(new ClassifierOutputStep()
                        .inputName(modelTrainResult.outputNames().get(0))
                        .labels(Arrays.asList(labels.clone()))
                        .allProbabilities(false)
                ).build()
        );

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://serving.konduit.ai/references/pipeline-steps.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
