Keras predict out of memory. You’ll learn how to calculate memory usage, identify key factors that influence it, and follow a step-by-step guide to find the largest input image size your GPU can handle without OOM errors. Dec 3, 2020 · The solution that ultimately worked, Include gc. My memory usage balloons while calling model. But it always causes CUDA_ERROR_OUT_OF_MEMORY when I predict images, even though I only predict a single file. Jul 18, 2019 · I use keras pre-trained InceptionResNetV2 to extract image features. Dec 7, 2022 · We have a tensorflow keras model which we would like to evaluate after training but the predict call after the training runs into out of memory errors even though the fit call works just fine. Predicting is the easy part. 0, and I also need to call clear_session and re-load the trained model periodically when in a predict loop in order to avoid running out of gpu memory. So tried to run the predictions this way, but found another bug; the images/txts saved by running the predictions ignore the original image names and save them as image0, image1, etc and so predictions for each Learn how to troubleshoot degraded training performance and memory issues in Keras. It involves taking the prepared input data (X) and calling one of the Keras prediction methods on the loaded model. clear_session () and gc. Using tf. If it is indeed an out of memory bug. 3. Jul 31, 2025 · I am using TF 2. I'm using a very large image data set with 1. Your home for data science and AI. Aug 9, 2021 · 6 I'm training a model for image segmentation using tf. Feb 23, 2023 · @glenn-jocher thanks! I think your changes by moving the results to cpu would solve the cuda memory issue, but still the out of the ram memory can be a potential issue as you mentioned. I really would like a fix to this. Dec 13, 2025 · In this blog, we’ll demystify GPU memory requirements for Keras models. 0 I'm getting crazy because I can't use the model I've trained to run predictions with model. I've done a similar thing before in keras, but am having trouble transfering the code to tensorflow. May 11, 2020 · OOM (Out Of Memory) errors can occur when building and training a neural network model on the GPU. Discover the causes of 'Out of Memory' errors in TensorFlow and learn effective strategies to solve them in this comprehensive guide. backend. e. You can try to set a small batch_size in predict. 2 million images, 15k classes, a Oct 8, 2019 · I'm building a model to predict 1148 rows of 160000 columns to a number of 1-9. keras and tensorflow version 2. predict () in a loop. keras using a custom data generator to read and augment images. 0. predict on Nov 9, 2020 Oct 19, 2023 · 1 I have a Keras model which consists of two parts (left and right), both working generally independently (due to a practical scenario), but these parts exchange some latent data generated by the model in intermediate steps. Model. I want to compress this latent data using autoencoders. Remember that the input for making a prediction (X) is only comprised of the input sequence data required to make a prediction, not all prior training data. The world’s leading publication for data science, data analytics, data engineering, machine learning, and artificial intelligence professionals. Oct 4, 2020 · Working on google colab. The size of the model is limited by the available memory on the GPU. 1, running on Ubuntu 18. Running the Nov 9, 2020 · plooney changed the title memory leak memory leak in tf. predict because it runs out of CPU RA Feb 9, 2017 · Graphs in train phase and in predict phase are usually different, so they can result in a different memory allocation resulting in different memory segmentation and different memory usage. Through strategic model optimization, careful resource management, and leveraging TensorFlow’s built-in capabilities, you can effectively mitigate these issues. Explore solutions for data pipelines, GPU utilization, and multi-GPU training. Jul 18, 2019 · Same issue. collect () and keras. Dec 20, 2024 · "Out of Memory" errors can be a significant obstacle in the machine learning workflow, but they are not insurmountable. keras. While training the model works fine (i. clear_session () after the model. collect () at the end of the loop. May 20, 2018 · I'm building an image classification system with Keras, Tensorflow GPU backend and CUDA 9. . predict (). With this, I could finally train the model with a constant disk usage. You can try to monitor the memory usage using nvidia-smi. Even with tf. without memory problems), when trying to predict on my test set my GPU (8GB, see nvidia-smi later) runs out of memory. 04. dgtyxycuvvifhpmignmggenaqvdluqwpemdmwyxpjygcpabnvat
