rdz-oss / battybirdnet-analyzer Goto Github PK

Hi, I am trying to run the bat_ident.py on Arch Linux. I did the following:

git clone https://github.com/rdz-oss/BattyBirdNET-Analyze
cd BattyBirdNET-Analyze
docker build . -t batty
docker run -v ~/bats:/home/bats -it batty bat_ident.py --area USA --i /home/bats/ --o /home/bats/out/ --rtype csv

But it printed e.g. Error: Cannot analyze audio file /home/bats/NoID_20240726_211812.wav.. After patching

Traceback (most recent call last):
  File "//bat_ident.py", line 281, in analyze_file
    prediction = predict(samples)
  File "//bat_ident.py", line 217, in predict
    prediction = model.predict(data)
  File "/model.py", line 308, in predict
    return predictWithCustomClassifier(sample)
  File "/model.py", line 351, in predictWithCustomClassifier
    feature_vector = embeddings(sample)
  File "/model.py", line 387, in embeddings
    features = INTERPRETER.get_tensor(OUTPUT_LAYER_INDEX)
  File "/usr/local/lib/python3.9/site-packages/tensorflow/lite/python/interpreter.py", line 888, in get_tensor
    return self._interpreter.GetTensor(tensor_index, subgraph_index)
ValueError: Tensor data is null. Run allocate_tensors() first

I can see in the code that allocate_tensors() is always run after tflite.Interpreter() calls so I'm not sure whats going on, maybe a version mismatch from the known working version (since the dockerfile installs the latest of everything)?

The classifier should be able to run 24/7 with a minimum of false alarms by environmental noise.
This requires samples of noise from different environments (say 10 of each type).

Hi,
I'm using a species list that fits the best the regions where I usually record bats. To to that I'm adding the flag --slist put-your-files-here/ where there's is my own species_list.txt. It works well but I noticed that at least one species (Pipistrellus nathusii) never appears anymore in the output. When I run the API with default species list, ie. no --slist flag, the species appears...
Can it be a bug somewhere or am I missing something in the spelling? To be sure I spelled correctly, I copied the english species list where I removed unwanted species.
Any hint?

Here is the content of my species_list.txt :

See discussion here: #3

Bat sounds are mostly out of reach of human hearing. Add a possibility to make human audible data. As not all humans are alike, aim for customizability and enable also low frequwncies, i.e. less than 7kHz versions.
