Amazon SageMaker is a fully-managed platform that enables developers and data scientists to quickly and easily build, train, and deploy machine learning models at any scale. cfg`) and: change line batch to `batch=64` change line `subdivisions` to `subdivisions=8` (if training fails after it, try doubling it) After selecting the directory of where you’ve saved your images in the pop-up GUI, you should see that two new files, train. I'm considering that "bounding box prior" is synonymous with "anchor". To do this, we need the Images, matching TFRecords for the training and testing data, and then we need to setup the You can use simple image processing to fix the size of the image to the desired resolution. Taehoon Lee took the pain of converting various popular networks’ weights into tensorflow’s format and has released a PyPi library called ‘Tensornets’. The mAP of the two models have a difference of 22. We use multi-scale training, lots of data augmentation, batch normalization, all the standard stuff.
