nable to create tensor, you should probably activate padding with 'padding=True' to have batched tensors with the same length.

Hi.

I am attempting to get bark set up on my local machine.

Here are the following steps that I have done:

1. Created an virtual environment and activated it
2. I've installed transformers package suing pip install transformers
3. Installed this library with pip install git+https://github.com/suno-ai/bark.git
4. And then basically copy and pasted the starter code in the readme file:

from transformers import AutoProcessor, BarkModel
import scipy
import os 

os.environ["SUNO_OFFLOAD_CPU"] = "True"
os.environ["SUNO_USE_SMALL_MODELS"] = "True"

processor = AutoProcessor.from_pretrained("suno/bark")
model = BarkModel.from_pretrained("suno/bark")

voice_preset = "v2/en_speaker_6"

inputs = processor("Hello, my dog is cute", voice_preset=voice_preset)

audio_array = model.generate(**inputs)
audio_array = audio_array.cpu().numpy().squeeze()

# write to a wav file:
sample_rate = model.generation_config.sample_rate
scipy.io.wavfile.write("bark_out.wav", rate=sample_rate, data=audio_array)

When I run this, I get the following two errors:

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.1.0 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

I'm a bit new to working with this library. Please assist if possible.

@goncastrum I'm not downloading a random file from mediafire. This will not fix my problem.

[bharattrader]

I think it is saying that numpy version should 1.x not 2.x. You can do a force uninstall and install.

[anudeike]

@bharattrader Just checked my numpy version: it is 1.26.4

[hvt1609]

It worked for me. Just switch numpy version to 2.x.x by "pip install -U numpy"
