            It looks like tensorflow only publishes wheels (and only up to 3.6), and Alpine linux is not manylinux1-compatible due to its use of musl instead of glibc. Because of this, pip cannot find a suitable installation candidate and fails. Your best options are probably to build from source or change your base image.

            The CD command means Change Directory.

            Once you have finished cloning Syntaxnet Github Repository, you should enter its directory. That's why you have to enter CD command.

            But have in mind that CD takes one parameter - the directory you want to enter.

            In order to solve your problem you must write cd syntaxnet resulting in:

            How to get Dependency Tree in JSON format in SyntaxNet?

            I am trying to get a dependency tree in JSON format from SyntaxNet but all I get from the examples is a Sentence Object which is providing no accessors to access the parsed object or even iterate through the items listed.

            Answered 2018-Aug-09 at 10:01

            TL;DR Code at the end...

            The Sentence object is an instance of the sentence_pb2.Setnence class, which is generated from protobuf definition files, specifically sentence.proto. This means that if you look at sentence.proto, you will see the fields that are defined for that class and their types. So you have a field called "tag" which is a string, a field called "label" which is a string, a field called head which is an integer and so on. In theory if you just convert to json using python's built-in functions it should work, but since protobuf classes are runtime generated metaclasses, they may produce some undesired results.

            So what I did was first created a map object with all the info I wanted, then converted that to json:

            A function that converts a dependency tree to a sequence of transitions is called an oracle. It is a necessary component of a statistical parser. The transitions you described (shift, reduce-l, reduce-r)¹ are those of the arc-standard transition system (not the arc-eager system, which is: shift, left-arc, right-arc, reduce).

            Pseudo-code for an arc-standard oracle:

            SyntaxNet to process a large number of sentences, do GPUs increase performance?
            Asked 2017-Apr-22 at 22:03

            I have a large dataset of sentences (i.e., ~5.000.000) in raw text which I want to process using SyntaxNet already trained for English. That is, I just want to process the sentences using a SyntaxNet model, I don't want to train any new model.

            Setting up a processing environment with GPUs will have any effect on performance ?

            I understand that most of the heavy CPU operations is on estimating the parameters and weights of the network/model, once these are estimated, applying the trained network should be faster than training.

            Nevertheless, I've never worked before with Tensorflow and I don't know whether GPUs are used when one applies an already trained model to data.

            Also, does anyone knows any easy way to setup SyntaxNet as a daemon or web-service, so that batch processing can be made easily?

            You still need to do a lot of tensor operations on the graph to predict something. So GPU still provides performance improvement for inference. Take a look at this nvidia paper, they have not tested their stuff on TF, but it is still relevant:

            Our results show that GPUs provide state-of-the-art inference performance and energy efficiency, making them the platform of choice for anyone wanting to deploy a trained neural network in the field. In particular, the Titan X delivers between 5.3 and 6.7 times higher performance than the 16-core Xeon E5 CPU while achieving 3.6 to 4.4 times higher energy efficiency.

            Regarding how to deploy your model, take a look at TF serving

            Based on some trial and error, I have arrived at the following minimums:

          • Train corpus - 18,000 tokens (anything less than that and step 2 - Preprocessing with the Tagger- fails)
          • Test corpus - 2,000 tokens (anything less than that and step 2 - Preprocessing with the Tagger - fails)
          • Dev corpus - 2,000 tokens

            But please note that with this, I've only managed to get the steps in the NLP pipeline to run, I actually haven't managed to get anything usable out of it.

            If you're using https://github.com/tensorflow/models/blob/master/syntaxnet/syntaxnet/demo.sh then the first metric is POS tag accuracy, the second UAS. They are only meaningful if the conll data you input contains gold POS tags and gold dependencies.
