-## Test a pretrained network
+## S3DIS Pretrained Models
+
+### Models
+
+We provide pretrained weights for S3DIS dataset. The raw weights come with a parameter file describing the architecture and network hyperparameters. THe code can thus load the network automatically.
+
+The instructions to run these models are in the S3DIS documentation, section [Test the trained model](./doc/scene_segmentation_guide.md#test-the-trained-model).
+
+
+| Name (link) | KPConv Type | Description | Score |
+|:-------------|:-------------:|:-----|:-----:|
+| [Light_KPFCNN](https://drive.google.com/file/d/14sz0hdObzsf_exxInXdOIbnUTe0foOOz/view?usp=sharing) | rigid | A network with small `in_radius` for light GPU consumption (~8GB) | 65.4% |
+| [Heavy_KPFCNN](https://drive.google.com/file/d/1ySQq3SRBgk2Vt5Bvj-0N7jDPi0QTPZiZ/view?usp=sharing) | rigid | A network with better performances but needing bigger GPU (>18GB). | 66.4% |
+
+
+
+### Instructions
+
+1. Unzip and place the folder in your 'results' folder.
+
+2. In the test script `test_any_model.py`, set the variable `chosen_log` to the path were you placed the folder.
+
+3. Run the test script
+
+        python3 test_any_model.py
+
+4. You will see the performance (on the subsampled input clouds) increase as the test goes on. 
+
+        Confusion on sub clouds
+        65.08 | 92.11 98.40 81.83  0.00 18.71 55.41 68.65 90.93 79.79 74.83 65.31 63.41 56.62
+
+
+5. After a few minutes, the script will reproject the results form the subsampled input clouds to the real data and get you the real score
+
+        Reproject Vote #9
+        Done in 2.6 s
+
+        Confusion on full clouds
+        Done in 2.1 s
+
+        --------------------------------------------------------------------------------------
+        65.38 | 92.62 98.39 81.77  0.00 18.87 57.80 67.93 91.52 80.27 74.24 66.14 64.01 56.42
+        --------------------------------------------------------------------------------------
+
+6. The test script creates a folder `test/name-of-your-log`, where it saves the predictions, potentials, and probabilities per class. You can load them with CloudCompare for visualization.
