            As you manually use the loss and metrics function in the train_step (not in the .compile) for the training set, you should also do the same for the validation set or by defining the test_step in the custom model in order to get the loss score and metrics score. Add the following function to your custom model.

            Apache Beam SIGKILL

            The Question

            How do I best execute memory-intensive pipelines in Apache Beam?

            Background

            I've written a pipeline that takes the Naemura Bird dataset and converts the images and annotations to TF Records with TF Examples of the required format for the TF object detection API.

            I tested the pipeline using DirectRunner with a small subset of images (4 or 5) and it worked fine.

            The Problem

            When running the pipeline with a bigger data set (day 1 of 3, ~21GB) it crashes after a while with a non-descriptive SIGKILL. I do see a memory peak before the crash and assume that the process is killed because of a too high memory load.

            I ran the pipeline through strace. These are the last lines in the trace:

            ANSWER

            Answered 2021-Jun-15 at 13:51

            Multiple things could cause this behaviour, because the pipeline runs fine with less Data, analysing what has changed could lead us to a resolution.

            Option 1 : clean your input data

            The third line of the logs you provide might indicate that you're processing unclean data in your bigger pipeline mmap(NULL, could mean that | "Get Content" >> beam.Map(lambda x: x.read_utf8()) is trying to read a null value.

            Is there an empty file somewhere ? Are your files utf8 encoded ?

            Option 2 : use smaller files as input

            I'm guessing using the fileio.ReadMatches() will try to load into memory the whole file, if your file is bigger than your memory, this could lead to errors. Can you split your data into smaller files ?

            Option 3 : use a bigger infrastructure

            If files are too big for your current machine with a DirectRunner you could try to use an on-demand infrastructure using another runner on the Cloud such as DataflowRunner

            Recommended way of measuring execution time in Tensorflow Federated
            Asked 2021-Jun-15 at 13:49

            I would like to know whether there is a recommended way of measuring execution time in Tensorflow Federated. To be more specific, if one would like to extract the execution time for each client in a certain round, e.g., for each client involved in a FedAvg round, saving the time stamp before the local training starts and the time stamp just before sending back the updates, what is the best (or just correct) strategy to do this? Furthermore, since the clients' code run in parallel, are such a time stamps untruthful (especially considering the hypothesis that different clients may be using differently sized models for local training)?

            To be very practical, using tf.timestamp() at the beginning and at the end of @tf.function client_update(model, dataset, server_message, client_optimizer) -- this is probably a simplified signature -- and then subtracting such time stamps is appropriate?

            I have the feeling that this is not the right way to do this given that clients run in parallel on the same machine.

            Thanks to anyone can help me on that.

            ANSWER

            Answered 2021-Jun-15 at 12:01

            There are multiple potential places to measure execution time, first might be defining very specifically what is the intended measurement.

            1. Measuring the training time of each client as proposed is a great way to get a sense of the variability among clients. This could help identify whether rounds frequently have stragglers. Using tf.timestamp() at the beginning and end of the client_update function seems reasonable. The question correctly notes that this happens in parallel, summing all of these times would be akin to CPU time.

            2. Measuring the time it takes to complete all client training in a round would generally be the maximum of the values above. This might not be true when simulating FL in TFF, as TFF maybe decided to run some number of clients sequentially due to system resources constraints. In practice all of these clients would run in parallel.

            3. Measuring the time it takes to complete a full round (the maximum time it takes to run a client, plus the time it takes for the server to update) could be done by moving the tf.timestamp calls to the outer training loop. This would be wrapping the call to trainer.next() in the snippet on https://www.tensorflow.org/federated. This would be most similar to elapsed real time (wall clock time).

            In your problem you are trying to use Sequential API to create the Model. There are Limitations to Sequential API, you can just create a layer by layer model. It can't handle multiple inputs/outputs. It can't be used for Branching also.

            Below is the text from Keras official website: https://keras.io/guides/functional_api/

            The functional API makes it easy to manipulate multiple inputs and outputs. This cannot be handled with the Sequential API.

            How to use hcl write to set expressions with ${}?
            Asked 2021-Jun-14 at 19:21

            I am trying to use hclwrite to generate .tf files.

            According to the example in hclwrite Example, I can generate variables like foo = env.PATH, but I don't know how to generate more forms of expressions. For example, the following.

            ...

            ANSWER

            Answered 2021-Jun-14 at 19:21

            The hclwrite tool currently has no facility to automatically generate arbitrary expressions. Its helper functions are limited only to generating plain references and literal values. SetAttributeValue is the one for literal values, and so that's why the library correctly escaped the ${ sequence in your string, to ensure that it will be interpreted literally.

            If you want to construct a more elaborate expression then you'll need to do so manually by assembling the tokens that form the expression and then calling SetAttributeRaw instead.

            In the case of your example, it looks like you'd need to generate the following eight tokens:

            • TokenOQuote with the bytes "
            • TokenQuotedLit with the bytes hello
            • TokenTemplateInterp with the bytes ${
            • TokenIdent with the bytes var
            • TokenDot with the bytes .
            • TokenIdent with the bytes stage
            • TokenTemplateSeqEnd with the bytes }
            • TokenCQuote with the bytes "

            The SetAttributeValue function is automating the simpler case of generating three tokens: TokenOQuote, TokenQuotedLit, TokenCQuote.

            You can potentially automate the creation of tokens for the var.stage portion of this expression by using TokensForTraversal, which is what SetAttributeTraversal does internally. However, unless you already have a parsed hcl.Traversal representing var.stage, or unless you need things to be more dynamic than you've shown in practice, I expect that it would take more code to construct that input traversal than to just write out the three tokens literally as I showed above.
