TFLite MicroInterpreter() never returns on Arduino Nano BLE 33 Sense

I am trying out the gesture recognization example using the **IMU_Classifier** example for detecting a "punch" gesture.
I see that the Arduino setup() code is kind of blocked when trying to initialize a MicroInterpreter() instance as below.

```
// Create a static memory buffer for TFLM, the size may need to
// be adjusted based on the model you are using
constexpr int tensorArenaSize = 8 * 1024;

byte tensorArena[tensorArenaSize];

tfLiteInterpreter = new tflite::MicroInterpreter(tfLiteModel,tfLiteOpsResolver, tensorArena, tensorArenaSize, &tfLiteErrorReporter);
```

Could you please share if this could be due to model size or any other dependency not being met? I gave it a try by shrinking model layers to reduce the model size as below but I still see an issue. Here, I am only trying to classify the punch gesture.

```
`# build the model and train it
model = tf.keras.Sequential()
model.add(tf.keras.layers.Dense(16, activation='relu'))
model.add(tf.keras.layers.Dense(8, activation='relu'))
model.add(tf.keras.layers.Dense(NUM_GESTURES, activation='sigmoid')) # softmax is used, because we only expect one gesture to occur per input
model.compile(optimizer='rmsprop', loss='mse', metrics=['mae'])
history = model.fit(inputs_train, outputs_train, epochs=600, batch_size=1, validation_data=(inputs_validate, outputs_validate))
`
```

Commencez par setup() de l’exemple IMU_Classifier et par l’initialisation de tflite::MicroInterpreter présentée sur l’Arduino Nano BLE 33 Sense. Vérifiez le modèle, la tensor arena de 8 KB et les dépendances indiquées afin de déterminer pourquoi l’initialisation ne revient jamais. C’est terminé lorsque la cause est identifiée et que l’exemple punch-classification peut terminer setup sans se bloquer.

Rédigé par le modèle d'indexation à partir du texte de l'issue.
