SetFit with flax-sentence-embeddings/stackoverflow_mpnet-base

This is a SetFit model that can be used for Text Classification. This SetFit model uses flax-sentence-embeddings/stackoverflow_mpnet-base as the Sentence Transformer embedding model. A LogisticRegression instance is used for classification.

The model has been trained using an efficient few-shot learning technique that involves:

Fine-tuning a Sentence Transformer with contrastive learning.
Training a classification head with features from the fine-tuned Sentence Transformer.

'In tf.gradients, there is a keyword argument grad_ys Why is grads_ys needed here? The docs here is implicit. Could you please give some specific purpose and code? And my example code for tf.gradients is'
'I am coding a Convolutional Neural Network to classify images in TensorFlow but there is a problem: When I try to feed my NumPy array of flattened images (3 channels with RGB values from 0 to 255) to a tf.estimator.inputs.numpy_input_fn I get the following error: My numpy_imput_fn looks like this: In the documentation for the function it is said that x should be a dict of NumPy array:'
'I am trying to use tf.pad. Here is my attempt to pad the tensor to length 20, with values 10. I get this error message I am looking at the documentation https://www.tensorflow.org/api_docs/python/tf/pad But I am unable to figure out how to shape the pad value'

"I am trying to use tf.train.shuffle_batch to consume batches of data from a TFRecord file using TensorFlow 1.0. The relevant functions are: The code enters through examine_batches(), having been handed the output of batch_generator(). batch_generator() calls tfrecord_to_graph_ops() and the problem is in that function, I believe. I am calling on a file with 1,000 bytes (numbers 0-9). If I call eval() on this in a Session, it shows me all 1,000 elements. But if I try to put it in a batch generator, it crashes. If I don't reshape targets, I get an error like ValueError: All shapes must be fully defined when tf.train.shuffle_batch is called. If I call targets.set_shape([1]), reminiscent of Google's CIFAR-10 example code, I get an error like Invalid argument: Shape mismatch in tuple component 0. Expected [1], got [1000] in tf.train.shuffle_batch. I also tried using tf.strided_slice to cut a chunk of the raw data - this doesn't crash but it results in just getting the first event over and over again. What is the right way to do this? To pull batches from a TFRecord file? Note, I could manually write a function that chopped up the raw byte data and did some sort of batching - especially easy if I am using the feed_dict approach to getting data into the graph - but I am trying to learn how to use TensorFlow's TFRecord files and how to use their built in batching functions. Thanks!"
"I am fairly new to TF and ML in general, so I have relied heavily on the documentation and tutorials provided by TF. I have been following along with the Tensorflow 2.0 Objection Detection API tutorial to the letter and have encountered an issue while training: everytime I run the training script model_main_tf2.py, it always hangs after the output: I tensorflow/compiler/mlir/mlir_graph_optimization_pass.cc:116] None of the MLIR optimization passes are enabled (registered 2) after a number of depreciation warnings. I have tried many different ways of fixing this, including modifying the train script and pipeline.config files. My dataset isn't very large, less than 100 images with a max of 15 labels per image. useful info: Python 3.8.0 Tensorflow 2.4.4 (Non GPU) Windows 10 Pro Any and all help is appreciated!"
'I found two solutions to calculate FLOPS of Keras models (TF 2.x): [1] https://github.com/tensorflow/tensorflow/issues/32809#issuecomment-849439287 [2] https://github.com/tensorflow/tensorflow/issues/32809#issuecomment-841975359 At first glance, both seem to work perfectly when testing with tf.keras.applications.ResNet50(). The resulting FLOPS are identical and correspond to the FLOPS of the ResNet paper. But then I built a small GRU model and found different FLOPS for the two methods: This results in the following numbers: 13206 for method [1] and 18306 for method [2]. That is really confusing... Does anyone know how to correctly calculate FLOPS of recurrent Keras models in TF 2.x? EDIT I found another information: [3] https://github.com/tensorflow/tensorflow/issues/36391#issuecomment-596055100 When adding this argument to convert_variables_to_constants_v2, the outputs of [1] and [2] are the same when using my GRU example. The tensorflow documentation explains this argument as follows (https://github.com/tensorflow/tensorflow/blob/master/tensorflow/python/framework/convert_to_constants.py): Can someone try to explain this?'

Uses

Direct Use for Inference

First install the SetFit library:

pip install setfit

Then you can load this model and run inference.

python

from setfit import SetFitModel

# Download from the 🤗 Hub
model = SetFitModel.from_pretrained("sharukat/so_mpnet-base_question_classifier")
# Run inference
preds = model("I'm trying to take a dataframe and convert them to tensors to train a model in keras. I think it's being triggered when I am converting my Y label to a tensor: I'm getting the following error when casting y_train to tensor from slices: In the tutorials this seems to work but I think those tutorials are doing multiclass classifications whereas I'm doing a regression so y_train is a series not multiple columns. Any suggestions of what I can do?")
