Converting teachable machine model into tflite format - python

So I have trained a posenet model for classifying different poses on the teachable machine learning website (link for the website). I want to use this trained model in a flutter app, and for that I need to convert the model into tflite format. I checked many online blogs which said that the website has an option of converting it to that format, but they have removed that feature. Thus, I wanted to know how can I convert this teachable machine model into tflite format?

I downloaded a pose model of my own from that site, and the zip appears to be a Tensorflow.JS model.
Now that we know the unzipped file is just a TF.js model, refer to a tutorial like this to convert the TFJS model back into a keras SavedModel, which can be then saved into a tflite model.

How to convert darknet image classification weights file to pytorch pt?

I created a model of darknet53.weights for image classification using my original data in darknet.
(This isn't a YOLO v3 model.)
Is there a way to convert a darknet53.weight to a pytorch pt model?
I tried quoting various codes on github etc., but all of them can convert only YOLOv3 weights file to pytorch's pt model.
I want to compare the accuracy of the darknet53 model created with darknet with other image classification models created with pytorch.
Initially, I tried to make a darknet53 model with pytorch, but that didn't work. Therefore, I created a darknet53 model with darknet.
If anyone knows a good way, please teach me.
Thanks.

How to use a trained Tensorflow Lite model in python?

I have a Tensorflow Lite model (.tflite file), which is already trained.
I need to use it in an API python view that receives recorded .wav files for speech recognition, and returns the equivalent text to the recorded file that was sent.
Any advices ou tutos on how I could use the trained model in order to treat the recorded instructions?
Thanks.
Refer to the TFLite Inference Guide for more details.
Specifically, for python refer to this

I use TFLiteConvert post_training_quantize=True but my model is still too big for being hosted in Firebase ML Kit's Custom servers

I have written a TensorFlow / Keras Super-Resolution GAN. I've converted the resulting trained .h5 model to a .tflite model, using the below code, executed in Google Colab:
import tensorflow as tf
model = tf.keras.models.load_model('/content/drive/My Drive/srgan/output/srgan.h5')
converter = tf.lite.TFLiteConverter.from_keras_model(model)
converter.post_training_quantize=True
tflite_model = converter.convert()
open("/content/drive/My Drive/srgan/output/converted_model_quantized.tflite", "wb").write(tflite_model)
As you can see I use converter.post_training_quantize=True which was censed to help to output a lighter .tflite model than the size of my original .h5 model, which is 159MB. The resulting .tflite model is still 159MB however.
It's so big that I can't upload it to Google Firebase Machine Learning Kit's servers in the Google Firebase Console.
How could I either:
decrease the size of the current .tflite model which is 159MB (for example using a tool),
or after having deleted the current .tflite model which is 159MB, convert the .h5 model to a lighter .tflite model (for example using a tool)?

How to decrease size of .tflite which I converted from keras: no answer, but a comment telling to use converter.post_training_quantize=True. However, as I explained it, this solution doesn't seem to work in my case.
In general, quantization means, shifting from dtype float32 to uint8. So theoretically our model should reduce by the size of 4. This will be clearly visible in files of greater size.
Check whether your model has been quantized or not by using the tool "https://lutzroeder.github.io/netron/". Here you have to load the model and check the random layers having weight.The quantized graph contains the weights value in uint8 format
In unquantized graph the weights value will be in float32 format.
Only setting "converter.post_training_quantize=True" is not enough to quantize your model. The other settings include:
converter.inference_type=tf.uint8
converter.default_ranges_stats=[min_value,max_value]
converter.quantized_input_stats={"name_of_the_input_layer_for_your_model":[mean,std]}
Hoping you are dealing with images.
min_value=0, max_value=255, mean=128(subjective) and std=128(subjective). name_of_the_input_layer_for_your_model= first name of the graph when you load your model in the above mentioned link or you can get the name of the input layer through the code "model.input" will give the output "tf.Tensor 'input_1:0' shape=(?, 224, 224, 3) dtype=float32". Here the input_1 is the name of the input layer(NOTE: model must include the graph configuration and the weight.)

Loading a trained model from Python to C++ in Tensorflow 1.2

I'm looking to run a basic fully-connected neural network for the MNIST dataset with the C++ API v1.2 from Tensorflow. I have trained the model and exported it using tf.train.Saver() in Python. This gave me a checkpoint file, a data file, an index file and a meta file.
I know that the data file contains the saved variables while the meta file contains the graph from using Tensorboard on a previous project.
However, I am not sure what is the recommended way to load those files
and run the trained model in a C++ environment in v1.2, since all the
tutorials and questions I've found are for older versions which differ
substantially.
I've found that tensorflow::ops::Restore should be the method to do such a thing, but I know that inference in Tensorflow isn't well supported, as such I am not certain what parameters should I give it in order to receive the trained model that I can just put into a session->Run() and receive an accuracy statement when fed test data.

How predict an image in google machine learning

I'm using Google cloud machine learning. I would like to identify different images.
Now I have trained my model with different type of image (using inception model of tensorflow), and I have created a version in Google machine learning with the results.
How can I get prediction about a new image?
Do you have some idea to help me?
Many thanks!
I'm not quite clear on what you're asking. Without more information, I will just point you to the Google blog post and code sample that detail how to train on images.
But back to what I think you're asking...for a model to be deployed to Google Cloud ML a few things have to happen:
It needs to have its inputs and output collections declared in the Tensorflow model before saving the checkpoint.
The model checkpoint needs to be copied to GCS
You must use gcloud to create a new "model" (as far as gcloud is concerned, a model is a namespace for many different tensorflow checkpoints) and then deploy your checkpoint to that gcloud model.
The prediction quickstart has a very similar example here.
