This page describes how to use the TensorFlow Lite converter using the command line tool. However, the Python API is recommended for the majority of cases. Use the Python API for any conversions involving optimizations, or any additional parameters e. The following flag can be used for compatibility with the TensorFlow 1. X version of the converter CLI:. To obtain the latest version of the TensorFlow Lite converter CLI, we recommend installing the nightly build using pip :.
Alternatively, you can clone the TensorFlow repository and use bazel to run the command:. If you are converting a model with a custom TensorFlow op, it is recommended that you write a TensorFlow kernel and TensorFlow Lite kernel. If the above is not possible, you can still convert a TensorFlow model containing a custom op without a corresponding kernel.
This ensures that the TensorFlow model is valid i. This is a list of an OpDef proto in string that needs to be additionally registered.

Any tensor returned by Session. You need to: encode the image tensor in some format jpeg, png to binary tensor evaluate run the binary tensor in a session turn the binary to stream feed to PIL image optional displaythe image with matplotlib Code: import tensorflow as tf import matplotlib.
I'm trying to follow the "Load using tf. In the tutorial, they can get away with only working with string Tensors, however, I need to extract the string representation of the filename, as I need to look up extra data from a dictionary. I can't seem to extract the string part of a Tensor. I'm pretty sure the. These are the three functions that I use to process the data Tensors from my dataset. The whole thing is proving difficult to debug as well, as I can't access attributes when debugging I get errors saying AttributeError: Tensor.

AAudibert AAudibert 4 4 silver badges 20 20 bronze badges. Thank you, but I decided that I should probably keep everything as tensors.
So now I'm outputting the values as a CSV file instead! I can read this file using tf. CsvDataset and then zip this file with the image dataset and then map them as tuples. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password.

Is it a missing feature in TensorFlow that tf.
In this, the Reader just read the file you give, so value is the content of the file, not the filename, but you can output key, then you get filename. Convert TensorFlow string to python string Where am I going wrong?
Giovan Cruz 1 Ujjwal Ujjwal 6 If you'd like to work with the string in Python, you need to execute the TensorFlow graph first. As you can see I have executed the graph inside a session. Although I have a feeling the reason you're not getting the result you want in the first approach is that this is binary data rather than a sensible filename. The tensor has been evaluated using eval. As to the validity of the data, it is valid since the tf. Hi, Ujjwal, have you ever solved this problem?
I'm looking for the solution. If I understand your issue correctly you can try: print filename. Ohad Meir Ohad Meir 2 Sign up or log in StackExchange.

Please be sure to answer the question. Provide details and share your research!To read data efficiently it can be helpful to serialize your data and store it in a set of files MB each that can each be read linearly.
This is especially true if the data is being streamed over a network. This can also be useful for caching any data-preprocessing. Protocol buffers are a cross-platform, cross-language library for efficient serialization of structured data.
Protocol messages are defined by. The tf. This notebook will demonstrate how to create, parse, and use the tf. Example message, and then serialize, write, and read tf. Example messages to and from. Fundamentally, a tf. Feature message type can accept one of the following three types See the.
Most other generic types can be coerced into one of these:. BytesList the following types can be coerced. FloatList the following types can be coerced.
Int64List the following types can be coerced. In order to convert a standard TensorFlow type to a tf. Example -compatible tf. Featureyou can use the shortcut functions below. Note that each function takes a scalar input value and returns a tf. Feature containing one of the three list types above:.
Below are some examples of how these functions work. Note the varying input types and the standardized output types. If the input type for a function does not match one of the coercible types stated above, the function will raise an exception e. All proto messages can be serialized to a binary-string using the.
SerializeToString method:. Suppose you want to create a tf. Example message from existing data. In practice, the dataset may come from anywhere, but the procedure of creating the tf. Example message from a single observation will be the same:.
Within each observation, each value needs to be converted to a tf. Feature containing one of the 3 compatible types, using one of the functions above. You create a map dictionary from the feature name string to the encoded feature value produced in 1. The map produced in step 2 is converted to a Features message. Consider a sample consisting of 10, independently and identically distributed observations from each of the above distributions:. Each of these features can be coerced into a tf.
You can then create a tf. Example message from these encoded features:. For example, suppose you have a single observation from the dataset, [False, 4, bytes 'goat'0. You can create and print the tf. Each single observation will be written as a Features message as per the above.
