            This error occurs when you have a sequence which contains integer values outside the range of the defined vocabulary size. You can reproduce your error with the following example, because the vocabulary size of the Embedding layer is 106, meaning sequences can have values between 0 and 105 and I pass a random sequence with values between 0 and 200 to enforce an error:

            I'm training a Seq2Seq model on Tensorflow on a ml.p3.2xlarge instance. When I tried running the code on google colab, the time per epoch was around 40 mins. However on the instance it's around 5 hours!

            If you're using SageMaker Notebook instance. Open a terminal and run nvidia-smi to see the GPU utilization rate. If you it's 0% then you're not using the right device. If it's more than 0% but very far from 100%, then you have a non GPU bottleneck to handle.
            If you're using SageMaker training, then check the GPU usage via Cloudwatch metrics for the job.

            The role of initial state of lstm layer in seq2seq encoder
            Asked 2021-May-16 at 18:34

            I am trying to follow this guide to implement a seq2seq machine tranlsation model: https://www.tensorflow.org/tutorials/text/nmt_with_attention

            The tutorial's Encoder has an initialize_hidden_state() function that is used to generate all 0 as initial state for the encoder. However I am a bit confused as to why this is neccessary. As far as I can tell, the only times when encoder is called (in train_step and evaluate), they were initialized with the initialize_hidden_state() function. My questions are 1.) what is the purpose of this initial state? Doesn't Keras layer automatically initialize LSTM states to begin with? And 2.) why not always just initialize the encoder with all 0 hidden states if encoder is always called with initial states generated by initialize_hidden_state()?

            Answered 2021-May-16 at 18:34

            you are totally right. The code in the example is a little misleading. The LSTM cells are automatically initialized with zeros. You can just delete the initialize_hidden_state() function.

            Save model after each epoch - AllenNLP
            Asked 2021-May-06 at 23:03

            Is there a parameter that I can set in the config file (maybe for the trainer?) that would save the model (archive) after each epoch or after a specific number of steps? I'm using seq2seq dataloader and "composed_seq2seq" as my model. This is how my trainer looks like currently:

            ANSWER

            Answered 2021-May-06 at 23:03

            Can you explain a little more about what you're trying to do with a model from every epoch/some number of steps? I think it already archives the model every time it gets a new best score, so I'm wondering what you want to do that can't be accomplished with that.

            Edit:

            It looks like AllenNLP already saves a model every epoch, but it only keeps a maximum of 2 by default. I believe you can change that by adding a checkpointer to your training config, e.g.:

            1. Please set add_special_tokens = False.
            2. Use tokenizer.convert_tokens_to_string (which takes the list of subword tokens as input), where tokenizer refers to the tokenizer used by your DatasetReader.

            Install seq2seq

            You can download it from GitHub.
            You can use seq2seq like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
