04. Deploy Model

Deploy the trained U-NetFor Option 1: Use the conda environment for Keras, which was already create in the previous exercise For Option 2: Use the conda environment for Tensorflow2, which was already create in the previous exercise Option 1: Deploy a Unet using No-Code nodes1. Reuse the Preprocessing Image component created in 01.Exercise to apply the identical preprocessing to the test data 2. Read in your U-Net from the previous exercise using the Model Reader node3. Use the Conda Environment Propagation node to ensure the correct conda environment (use the Keras environment created in the beginning under Preferences) is selected. 4. Use the Keras Network Executor node to apply the trained model on the test data - connections: - use the preprocessed test data as input - use the model from the Model Reader as model input - connect the conda environment flow variable from the Conda Environment Propagation node to the Flow Variable input port - Node Settings: - input column: preprocessed image column "Img Calc" - add output: select "conv2d_19/Sigmoid:0", Conversion: "To Image", rename column "output" - Executable Selection tab: select conda environment flow variable5. After converting the predicted image to labels, use the Interactive Segmentation View node to evaluate your prediction results Option 2: Deploy a Unet using Tensorflow2 nodes1. Reuse the Preprocessing Image component created in 01.Exercise to apply the identical preprocessing to the test data 2. Use the Conda Environment Propagation node to ensure the correct conda environment (use the Tensorflow2 environment created in the beginning under Preferences) is selected. 3.

Use the Tensorflow2 Network Executor node to apply the trained model on the test data - connections: - use the preprocessed test data as input - use the model from the Tensorflow2 Network Reader as model input - Node settings: - input columns: preprocessed image column "Img Calc" - add output: select "conv2d_19/Sigmoid:0", Conversion: "To Image", rename column "output" - Executable Selection tab: select conda environment flow variable5.
