尝试将 SCRIPT vl_imreadjpeg 作为函数执行:
C:\Users\Administrator\Desktop\matconvnet-fcn-master\matconvnet\matlab\vl_imreadjpeg.m
出错 getBatch (line 52)
rgb = vl_imreadjpeg({rgbPath}) ;
出错 fcnTrain>@(imdb,batch)getBatch(imdb,batch,opts,'prefetch',nargout==0) (line 107)
fn = @(imdb,batch) getBatch(imdb,batch,opts,'prefetch',nargout==0) ;
出错 cnn_train_dag>process_epoch (line 178)
inputs = state.getBatch(state.imdb, batch) ;
出错 cnn_train_dag (line 89)
stats.train(epoch) = process_epoch(net, state, opts, 'train') ;
出错 fcnTrain (line 98)
info = cnn_train_dag(net, imdb, getBatchWrapper(bopts), ...

Anyone Kindly help me or give some code to solve this issue...
Waiting for your positive response...
thank you...
