How To Calculate A Net’s Flops In CNN

I don't use image augmentation, so I think the miscellaneous memory would be only related to the mini-batch size. I'm using a mini-batch size of images. I'm using TensorFlow and I think I'm missing something. I haven't run the training yet, but I'm pretty sure based on past experiences that the memory in use will be much higher than what I've calculated.

If that is the case, then I'd need more Can you help me understand the memory considerations for training my deep learning model? Are the above considerations right? Yes, you will need to store the derivatives of the activations and of the parameters for backpropagation.

Additionally, your choice of optimization may matter. These will all have different memory requirements. For example, you're going to have to store the step size cache for a momentum-based method, although that should be secondary compared to the other memory considerations you mention.

So all in all, you seem to have calculated the memory requirements for a forward pass.

Andrej Karpathy mentions that the backward pass could take up to 3x the memory of the forward pass, so this might be why you see such a difference scroll down to 'Case Studies' on the website to see an example for VGGNet.

Total Memory: 4. Someone please correct me on this if I'm wrong. FYI, you already multiplied miscellaneous byso that's why I didn't multiply it by above.

We noticed you have not filled out the following field in the issue template. Have you read the caveats on floating point profiling?

It looks like some of these may apply to your case? Yes, I've read the caveats. In my example, all the shapes are well defined and there's not ambiguity no tf.

I took one of the simplest case possible: one matrix multiplication. As the docs note, contributions here would be welcome. Are you interested in looking into this issue?

Lines to in f04a. It has been 29 days with no activity and the awaiting response label was assigned. Is this still an issue? Closing due to staleness.

Please use the latest version for TensorFlow and test again. Feel free to open a new issue if it still persists. You initialize a result matrix filled with zeros and then you add to each entry the result of the row x column multiplication.

This way, one entry of the result matrix requires p multiplications, which are summed using p-1 summations. By adding it to the result matrix, you obtain one additional flop, yielding.

Allow me, if you will, to ask why you are so paranoid about this? I can assure you that your computer's flops are lacking, mostly because of it being a laptop with mobile parts, plus by the sounds of it, no dedicated GPU, as even a mobile GPU chip would be a hefty increase. Was your old computer a laptop or desktop? Currently playing Path of Exile: Delirium! EDIT: evn was already grinding out a massive post that details it further when I wrote this I think I should point out that "FLOPS" is a theoretical calculation, and not really useful for anything other than showing changes in technology over time.

Not only that, but a CPU with a higher FLOP rating may perform worse than one with a lower rating, due to software design, core and thread efficiency, OS, and a lot of other things. Effectively what I'm saying is If you want to test how good your CPU is compared to your old one Hardly enough time for a prelude.

When it came to visiting agony, the Romans were hobbyists. Intel Burn test gives results in GFlops. Not sure if it's in any way useful.

Well flops don't mean everything really.

Taking the cell cpu as example it did have higher Gflops than the xbox's chip but it wasn't better at all mainly because the cell cpu was just weak in symmetric multithreading and being a true single core not an 8 as they advertized it.

It's also possible to use the profiler in combination with Keras like the following snippet:. I would like to build on Tobias Schnek's answer as well as answering the original question: how to get FLOP from a pb file. The answer is in the way the tensors A and B are initialised. Changing the definition of A and B by. Usually, a network's variables are initialised with Gaussian distributions among other schemes. Most of the time, we are not interested by the initialisation FLOP as they are done once during initialisation and do not happen during the training nor the inference.

Freeze the graph with a pb. An issue has been opened to understand why. The above approaches no longer work for TF2. Seems like this feature still needs to be implemented.

I build on this answer to explain it. It works like a charm.By Matthew Scarpino. Machine learning applications are fundamentally mathematical, and TensorFlow provides a wealth of routines for performing mathematical operations on tensors.

Each routine is represented by a function of the tf package, and each function returns a tensor. When it comes to TensorFlow operations, its best to start simple. The following table lists 12 functions that perform basic math operations. The first four functions perform element-wise arithmetic. The following code demonstrates how they work:. For example, the following two lines of code create the same tensor:. When operating on floating-point values, div and divide produce the same result.

But for integer division, divide returns a floating-point result, and div returns an integer result. The following code demonstrates the difference between them:. In contrast, the divide function performs Python-style division. Matthew Scarpino has been a programmer and engineer for more than 20 years. He has worked extensively with machine learning applications, especially those involving financial analysis, cognitive modeling, and image recognition.

For even length tensors, the default behaviour is to output one of the two elements rather than their average. In general, the second method will give us the correct median for a list of both even and odd lengths but it will be slower. TensorFlow Print - Print the value of a tensor object in TensorFlow by understanding the difference between building the computational graph and running the computational graph.

AI Workbox. Up next. Calculate TensorFlow Median Value tf. We can find the median using the percentile function. The function is in tf. The first argument to the function is the tensor whose median we want to find. Next, we can run this as a session which outputs the median tensor 3. Session as sess: sess. For this behavior, we can use one of the interpolation options.

Here, our median should be 3. The median can simply be computed by adding these two tensors and dividing by two. So these are two different methods that you can use to find the median of a tensor.

Level-up, accomplish more, and do great work!It allows categorizing data into discrete classes by learning the relationship from a given set of labeled data.

It learns a linear relationship from the given dataset and then introduces a non-linearity in the form of the Sigmoid function. In case of Logistic regression, the hypothesis is the Sigmoid of a straight line, i. Let us visualize the Sigmoid Function —.

tensorflow calculate flops

Output: Note that the range of the Sigmoid function is 0, 1 which means that the resultant values are in between 0 and 1. This property of Sigmoid function makes it a really good choice of Activation Function for Binary Classification. Just like Linear Regression, we need to find the optimal values of w and b for which the cost function J is minimum.

In this case, we will be using the Sigmoid Cross Entropy cost function which is given by This cost function will then be optimized using Gradient Descent. Implementation: We will start by importing the necessary libraries. Next we will be importing the dataset. We will be using a subset of the famous Iris dataset.

Now we will be One Hot Encoding the data for it to work with the algorithm. One hot encoding transforms categorical features to a format that works better with classification and regression algorithms. We will also be setting the Learning Rate and the number of Epochs. Now we will start creating the model by defining the placeholders X and Yso that we can feed our training examples x and y into the optimizer during the training process.

We will also be creating the trainable Variables W and b which can be optimized by the Gradient Descent Optimizer. Now we will be plotting the Decision Boundary for our trained classifier. A decision boundary is a hypersurface that partitions the underlying vector space into two sets, one for each class.
