当我运行下面这个代码的87行的时候，遇到了如下报错

[targets,predictors] = gather(targets,predictors);

下面是错误日志

[targets,predictors] = gather(targets,predictors);
正在使用 Parallel Pool 'local' 计算 tall 表达式:
- 第 1 次遍历(共 1 次): 用时 2 分钟 23 秒
计算已完成 91%
错误使用 matlab.io.datastore.TallDatastore/hasdata (第 33 行)
计算 tall 表达式时出现内部问题。问题为:

出错 matlab.bigdata.internal.io.LocalReadProcessor/process (第 55 行)
obj.IsFinished = ~hasdata(obj.Reader);

出错 matlab.bigdata.internal.executor.CompositeDataProcessor>iProcess (第 147 行)
data = process(processor, data{:});

出错 ...
    
出错 tall/gather (第 50 行)
[varargout{:}, readFailureSummary] = iGather(varargin{:});

原因:
错误使用 matlab.io.datastore.TallDatastore/hasdata (第 33 行)

I understand that you got a parallel pool error when you run the example –“https://www.mathworks.com/help/deeplearning/ug/denoise-speech-using-deep-learning-networks.html”

The example takes around 60-70 minutes to run, make sure you keep your MATLAB editor active and have a proper network connection. This will help in avoiding inactive parallel pool error.

I am unable to reproduce the same error while running the ‘Denoise Speech Using Deep Learning Networks’ example in R2023a MATLAB version.

you can try updating the MATLAB version and then run the example.

Hope it helps!
