RuntimeError：无法缓存函数“ __jaccard”：文件“ /usr/local/lib/python3.7/site-packages/librosa/util/matching.py”没有可用的定位器

问题描述

我正在docker Windows10计算机上的flask应用程序。在docker运行后出现以下错误

I am dockerising the flask application on windows10 machine.I get the below error after the docker run

RuntimeError：无法缓存函数'__jaccard'：no定位器可用于文件'/usr/local/lib/python3.7/site-packages/librosa/util/matching.py'

flask应用程序

我指的是类似的帖子：

i referred to kind of similar post: numba caching issue: cannot cache function / no locator available for file

我已在Dockerfile中添加了该应用程序的用户访问权限。

i have added the user access permissions for the application in the Dockerfile.

1。 Dockerfile

FROM python:3.7.3

RUN useradd admin

COPY . /app

WORKDIR /app

RUN pip install -r "requirements.txt"

RUN chown -R admin:admin /app

RUN chmod 755 /app

USER admin

ENTRYPOINT ["python"]

CMD ["app.py"]

2。 requirements.txt

flask
tensorflow
flask_cors
uuid
librosa
numba
pysoundfile
numpy
cffi
requests
wave
h5py
pydub
werkzeug

3。错误日志：

推荐答案

我已经通过安装旧版本解决了该问题。

I've solved the problem by installing old version.

pip install librosa==0.6.0
