为 TensorFlow 导入 librosa 时出错：找不到 sndfile 库

Question

I'm trying to use TensorFlow Lite for a voice recognition project using Jupyter notebook but when I try to do a "import librosa" (using commands found here: https://github.com/ShawnHymel/tflite-speech-recognition/blob/master/01-speech-commands-mfcc-extraction.ipynb ) I keep getting this error:

OSError: sndfile library not found

I've looked for a solution for two days now, tried many different things I've found online but I just can't seem to get it to work.

I'm using CentOS 8 and the tensorflow is running on a docker:

docker pull tensorflow/tensorflow:latest-py3-jupyter   
docker run -it --rm -v /home/server/Desktop/TensorFlow -p 8888:8888 tensorflow/tensorflow:latest-py3-jupyter

My requirements.txt is empty, at least when I do pip freeze > requirements.txt .

pip -V or --v returns this

pip 20.3.2 from /usr/local/lib/python3.6/site-packages/pip (python 3.6)

Trying to install pysndfile gives me this

ERROR: Command errored out with exit status 1: /usr/bin/python3 /usr/local/lib/python3.6/dist-packages/pip install --ignore-installed --no-user --prefix /tmp/pip-build-env-w_gdqebo/overlay --no-warn-script-location --no-binary :none: --only-binary :none: -i https://pypi.org/simple -- setuptools 'numpy>=1.13.0' 'cython>=0.25.0' wheel Check the logs for full command output.

I've tried different commands to fix this error and to install the sndfile but all of them have given errors or simply said it's already installed.

I do have librosa installed but trying to import it gives me this full error:

    143     _snd = _ffi.dlopen(_libname)
    144 except OSError:

OSError: sndfile library not found

Anyone got ideas on how to sort this?

Answer 1

Install sndfile for your operating system. On CentOS that should be yum install libsndfile .
