DETECTRON2 - Training on Custom Dataset 🔥🔥

#detectron2 #theartificialguy #deeplearning
Hello all, so it took me a while creating this video and finally I came up with it. So, in this video, we will be training DETECTRON2 on a CUSTOM dataset. I used Skin Disease dataset for this tutorial. The same procedure can be applied on any other kind of dataset.
Do check out my previous video in which I have implemented 4 Advanced Computer Vision tasks like Object detection, Keypoints detection, Instance segmentation and Panoptic segmentation.

Great video!!! You might've saved me from an entire day of head scratching. Thanks!!! 🤟

[@soul931]

Cool

[@leedida2134]

thank you for uploading this video. it helped me a lot, i tried to implement this detectron2 in my project, and i completely seen my custum data work. thank you for sharing. thanks!

[@kou9999ful]

Great Video. Can you explain the part of labelling for panoptic segmentation as well? How should we add instance ids to the json file?

[@adibahaque3482]

This is such a great tutorial. Can you please make a tutorial using Vision Transformer for training on custom dataset for instance segmentation task?

[@makethisfacefamous3650]

Hi bro can you do a video for panoptic segmentation with custom data training please

[@abbasabdulsalambamidele8760]

Thank you for the video. Could you help me with how to use a different backbone? like googlenet instead of resnet. Thanks in advance

[@SchoolofAI]

This is a really great tutorial. It's perfectly paced and explained everything without explaining too much that's not needed for the specific task of training a model using custom data. Great work.

[@coder5199]

​@@theartificialguy6898 Hi thanks for this video. There are TONS of YT vids on Detectron2 for object detection and instance segmentation but NONE on semantic segmentation for custom datasets. Can you be the one that fill the gap?

[@inquisitiverakib5844]

Very helpful video... How can we perform evaluatio of the trained model ? Plz help

[@yhnshkn]

thanks for the tutorial! can you also please create a video on how to load trained models?

[@muhammadatique4293]

Great effort. I suppose you make modification ti available tutorial of detectron2 on collab notebook

[@Mrbeeastzshortz]

Can you please let me know how can I input the video in this and get the video with bounding boxes and mask

[@bahubalipatil9432]

how can we get approx size of the object cm from mask? or is there any way to do it? can it be done while labelling the images if yes then how?

[@chitranjankumarrai1799]

COOL

[@kartikkuri336]

Why it's showing as segmentation when we're need detection

[@humayunkabir548]

i have a validation data set as well. how can I use them or how can I edit the code in order to use the validation data,so that I can see the validation loss and training loss curve,to comment on if its underfitting or overfitting. Please response

[@jakobbrsomo5078]

great tutorial. thanks

[@mdiftekherhossain6152]

Nice One!

[@mohammadrajabi3152]

Thank you very much for this tutorial. unfortunately i have a error KeyError: 'imagePath' on my trainer. I checked every single code for that but i found anything incorrect. please help meeeee !!!!

[@nagendravishwakarma9278]

did you solve this error bcd i also got the same key error ?

[@andianzanulzikra5729]

can you help me to add a line of code to calculate the evaluation of the mAP training model?

[@samiulhaque3338]

pytorch 1.9 is indeed compatible.

amazing god job

[@bhuvanbhuvi8959]

Instead of showing the predictions in an image how can i get names of predictions?

[@theye050505]

Thank you for the video. Where is the colab link?

[@siddharthrana512]

This code is not going to work when we send a fresh image for prediction with annotations

[@gemshunt9637]

hi! Great tutorial! Help me please, how i can convert "pth" format to "onnx"? I want to use this in opencv. Help me please!!!!!!!

[@tugbayildizli3828]

Thanks for the video. FileNotFoundError: [Errno 2] No such file or directory: '/content/drive/MyDrive/datasets/train/..\\images\\potholedataset_(1).jpg' Why cannot it find the image file? It shows up in the trainer.train() step.

[@theartificialguy6898]

Please double check your path, or you can just try to read an image from your directory to make sure you've set the correct path, something like : img = cv2.imread("your_path_here") Or if you're using colab you can open file navigation from left panel and right click on any image then select "copy path" and double check it. Or you can type "pwd" in a cell to get the current working directory full path and use that instead... Hope it works!

[@namandwivedi5652]

while running "trainer = DefaultTrainer(cfg)" i am getting the error that Cuda is not available. How to fix that problem

[@IamCoderGirl]

in colab first set the path runtime as GPU

[@ManuelHernandez-zq5em]

Great video! And your code worked well with no issues! Thank you! Question: Once I am done training the model, is there a way to download it (as a file) to use it by inference on a Python program running in my local laptop?

[@Imdeepmind]

You can download the model directly from Colab and use it locally.

[@ManuelHernandez-zq5em]

@@Imdeepmind Oh yes. Thank you. I have another question. How can I export an ONNX model out of this model? I have been breaking my head looking online and all I find are samples on existing models from model zoo but, nothing on a custom model. Any ideas? 😕

[@Игорь-ж9р5ж]

I get the error as: AttributeError: _func in detectron2/engine/hooks.py how can i solve it?

[@JoelPrabhod]

can you also add a few lines of code to evaluate the model?

[@VBFilms]

So why do the test data also have to have the JSON-file? I thought that I could just upload pictures without any labeling to a trained model and only the training data would require the labeling?

[@abheeshtamn6027]

My exact question!

[@limhz2630]

where can i get the same code shown in colab

[@syalwadea]

how to predict a new images without labeling? :(((

[@syalwadea]

i mean how to use a model with a new image? :D i need your help

[@theartificialguy6898]

@@syalwadea Hi, you could do something like this: ``` from detectron2.engine import DefaultPredictor from detectron2.config import get_cfg cfg = get_cfg() cfg.MODEL.WEIGHTS = os.path.join("path_to_your_model_file.pth") cfg.MODEL.ROI_HEADS.NUM_CLASSES = 2 // your task num classes cfg.MODEL.ROI_HEADS.SCORE_THRESH_TEST = 0.5 predictor = DefaultPredictor(cfg) img = cv2.imread("path _to_img") outputs = predictor (img) And then the same code for visualization, i hope it helped! ```

[@owen261]

Amazing tutorial. How do I test it on data that does not have json files? just a 100% new image.

[@syalwadea]

are you find the answer? :(

[@dk_x.095]

Dataset link not working

[@priyanshmishra7460]

the code is showing "No CUDA GPUs are available" error, please help!

[@namandwivedi5652]

Did you get the answer

[@Samurai-in5nr]

Can these steps be used for detecting key point of animals like dogs? If yes how can i do so can u please give a little bit of advice or Not is there any way to acheive this without using any state-of-art libraries like mmpose and deeplabcut?

[@zehra2334]

why not? But first of all, you should create the coordinates...

[@prashantsharmastunning]

hi , i have trained the model on custom dataset, and the total loss is decreasing also, but while prediction its not predicting anything, just printing grayscale images. please help

[@prashantsharmastunning]

@@shradhasharma4260 lower the confidence score

[@zehra2334]

thanks for the video! But also, your microphone is not in a good situation, I think.

[@bhawanishankarsahu7577]

bro i need a file to run this model directily on single image can you help me

[@rebeccac7735]

I keep getting an error message, No such file or directory: '/content/drive/MyDrive/datatrain', when I run the trainer. Any help would be appreciated!

[@theartificialguy6898]

Please check the path that you are using and make sure you have the file on that directory you mentioned!

[@mohammadrajabi3152]

put a / at the end of your path

Well the tutorial worked and i used it to classifie street signs but in testing it didn´t recognise something in the picture could someone help me with that?

how you tackle this issue? bec i am also facing the same problem :/

Can anyone tell how to change the size of images

how to deploy it in mobile phone or coverting it to tensorflowlite

Will make a tutorial soon!

Man, I created a customized model with 3 classes (A, B and C). And I would like to take especific masks for a especific object. And I use this code: mask_A = outputs['instances'].pred_masks.cpu().numpy()[0]

Dose detectron2 runs on rtx3090 ?
