+                
+                ⌛️ It takes about 20~ seconds to generate 4 samples, to get faster results, don't forget to reduce the Nº Samples to 1.

+                You can obtain the Segmentation Map of any Image through this Colab: [![Open in Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/github/mfidabel/JAX_SPRINT_2023/blob/main/Segment_Anything_JAX_SPRINT.ipynb)

+        # 👨‍💻 About the model
+        
+        This [model](https://huggingface.co/mfidabel/controlnet-segment-anything) is based on the [ControlNet Model](https://huggingface.co/blog/controlnet), which allow us to generate Images using some sort of condition image. For this model, we selected the segmentation maps produced by Meta's new segmentation model called [Segment Anything Model](https://github.com/facebookresearch/segment-anything) as the condition image. We then trained the model to generate images based on the structure of the segmentation maps and the text prompts given.
+        
+
+        
+        # 💾 About the dataset
+        
+        For the training, we generated a segmented dataset based on the [COYO-700M](https://huggingface.co/datasets/kakaobrain/coyo-700m) dataset. The dataset provided us with the images, and the text prompts. For the segmented images, we used [Segment Anything Model](https://github.com/facebookresearch/segment-anything). We then created 8k samples to train our model on, which isn't a lot, but as a team, we have been very busy with many other responsibilities and time constraints, which made it challenging to dedicate a lot of time to generating a larger dataset.  Despite the constraints we faced, we have still managed to achieve some nice results 🙌
+
