Aryn OCR Deployment Guide¶

Starting 11.4 Datarobot allows to enable enhanced Optical Character Recognition via Aryn Software. Datarobot installation bundle includes an image required to run Aryn service in any cloud. The service also requires GPU nodes available in Kubernetes.

Requirements¶

Minimal GPU requirements:

GPU Device	GPU Memory	RAM	CPU Cores	Storage	VM Types
Nvidia T4/L4	16GiB	32GiB	8	200GiB	Azure: Standard_NC4as_T4_v3 AWS: g4dn.2xlarge Google Cloud: g2-standard-8

Recommended GPU nodes:

GPU Device	GPU Memory	RAM	CPU Cores	Storage	VM Types
Nvidia T4/L4	24GiB	64GiB	16	200GiB	Azure: Standard_NC16as_T4_v3 AWS: g6.4xlarge Google Cloud: g2-standard-16

Optional: Labeled Nodes¶

Once Aryn is launched no other pod can share the node with Aryn installation. It is important that Aryn won't be launched on a high-cost GPU like H100 or similar, unless required. Thus, it is recommended to label node(s) to be used to launch Aryn, for example:

kubectl label nodes <your-node-name> datarobot.com/node-capability=aryn-gpu

or make sure that the nodes are provisioned with the label.

Enablement¶

Override configuration with:

global:
  aryn_ocr:
    enabled: true

  ocr-service:
    enabled: true

  aryn-ocr:
    # Set selector if nodes where specifically labeled based on `Optional: Dedicated Nodes` section
    nodeSelector:     
      "datarobot.com/node-capability": aryn-gpu
    nodeAffinity:
      enabled: false

Extras¶

Aryn OCR service configuration also supports taints and tolerations for better node allocation to make sure that a labeled node will not be occupied by any other service: - Assign your node an additional taint: dedicated=aryn-ocr:NoExecute - Override configuration with:

global:
  aryn_ocr:
    enabled: true

  ocr-service:
    enabled: true

  aryn-ocr:
    # Set selector if nodes where specifically labeled based on `Optional: Labeled Nodes` section
    nodeSelector:     
      "datarobot.com/node-capability": aryn-gpu
    nodeAffinity:
      enabled: false
    tolerations:
      # Allow scheduling on nodes with GPU taint
      - key: "nvidia.com/gpu"
        operator: "Exists"
        effect: "NoExecute"
      - key: "dedicated"
        operator: "Equal"
        value: "aryn-ocr"
        effect: "NoExecute"
