That's it. Now we have two images for patches and labels. If we wanna, we can split them to distinguish test/validation groups (with the **ExtractROI** application for instance). But here, we will just perform some fine tuning of our model, located in the `outmodel` directory. Our model is quite basic. It has two input placeholders, **x1** and **y1** respectively for input patches (with size 16x16) and input reference labels (with size 1x1). We named **prediction** the tensor that predict the labels and the optimizer that perform the stochastic gradient descent is an operator named **optimizer**. We perform the fine tuning and we export the new model variables in the `newvars` folder.
Let's use our **TensorflowModelTrain** application to perform the training of this existing model.
```
otbcli_TensorflowModelTrain -model.dir /path/to/oursavedmodel -training.targetnodesnames optimizer -training.source1.il samp_patches.tif -training.source1.fovx 16 -training.source1.fovy 16 -training.source1.placeholder x1 -training.source2.il samp_labels.tif -training.source2.fovx 1 -training.source2.fovy 1 -training.source2.placeholder -y1 -model.saveto newvars
otbcli_TensorflowModelTrain -model.dir /path/to/oursavedmodel -training.targetnodesnames optimizer -training.source1.il samp_patches.tif -training.source1.fovx 16 -training.source1.fovy 16 -training.source1.placeholder x1 -training.source2.il samp_labels.tif -training.source2.fovx 1 -training.source2.fovy 1 -training.source2.placeholder y1 -model.saveto newvars
```
Note that we could also have performed validation in this step. In this case, the `validation.source2.placeholder` would be different than the `training.source2.placeholder`, and would be **prediction**. This way, the program know what is the target tensor to evaluate.
