ModuleNotFoundError: No module named 'acconeer.exptool.a121._core.peripherals'

[thedevleon]

I'm trying to run the model_deployment.ipynb notebook and have the acconeer-exptool installed in a venv with python 3.12.
I can open the exptool-app just fine.

> pip install acconeer-exptool                                                                                                                                                                   
Requirement already satisfied: acconeer-exptool in ./venv/lib/python3.12/site-packages (7.7.1)

> python -m acconeer.exptool.app
[Exploration Tool opens...]

However, trying to run the first cell in the notebook already gives me an error:

from util import get_processing_config
processing_config = get_processing_config()
print("Gesture Detection classes:", processing_config["gd_gestures"])
print("Gesture Classification classes:", processing_config["gc_gestures"])

ModuleNotFoundError: No module named 'acconeer.exptool.a121._core.peripherals'

Do I need to install a different version of the exptool?

Also, maybe related, but I cannot open any of the recordings in /data either, see acconeer/acconeer-python-exploration#134

[thedevleon]

Fixed by installing

pip install acconeer-exptool==6.0.5

The version of the exptool should really be pinned somewhere, i.e. a requirements.txt

You can change the import line in utils.py file

acconeer-a121-gesture-control/util.py

Line 3 in e70494a

from acconeer.exptool.a121._core.peripherals import load_record

to

from acconeer.exptool.a121 import load_record

The same thing can be done with the import line in realtime_deployment.py file

acconeer-a121-gesture-control/realtime_deployment.py

Line 14 in e70494a

from acconeer.exptool.a121._core.peripherals import load_record

To run the file, you also need to do some additional modification due to changing in numpy and keras

• In model_development.ipynb,
  • in the line segments = np.concatenate((segments, np.array([features[i:i+gd_window_length]], dtype=np.float)), axis=0), change np.float to float.
  • in the box which has

gc_model = Sequential(normalization_layer)
gc_model.add(Dropout(0.2))
gc_model.add(LSTM(40, recurrent_dropout=0.2, input_shape=(None, gc_X_train.shape[2])))
gc_model.add(Dense(units=30, activation='relu'))
gc_model.add(Dropout(0.2))
gc_model.add(Dense(units=20, activation='relu'))
gc_model.add(Dropout(0.2))
gc_model.add(Dense(len(gc_gestures), activation='softmax'))

change to

gc_model = Sequential([
    normalization_layer,
    Dropout(0.2),
    LSTM(40, recurrent_dropout=0.2, input_shape=(None, gc_X_train.shape[2])),
    Dense(30, activation='relu'),
    Dropout(0.2),
    Dense(20, activation='relu'),
    Dropout(0.2),
    Dense(len(gc_gestures), activation='softmax')
])
