scipy.io.matlab.miobase.MatWriteError: Matrix too large to save with Matlab 5 format

python 读写Matlab mat v7.3文件

Introduction — hdf5storage 0.1.14 documentation

问题：
一开始想使用scipy.io保存.mat文件(sio.savemat())，但是疯狂报错MatWriteError: Matrix too large to save with Matlab 5 format

解决方案：
使用hdf5storage.savemat()即可

具体方法：

pip install hdf5storage

# layer_data = {'keys': item, 'values': feature_all[item]}
# sio.savemat(save_name, layer_data)
keys = list(feature_all.keys())
values = list(feature_all[item])
layer_data = {'keys': item, 'values': values}
# hdf5storage.savemat(save_name, layer_data ,do_compression=True, format='7.3')   
hdf5storage.savemat(save_name, layer_data, format='7.3', matlab_compatible = True) 

 # 读出mat文件

matcontent = hdf5storage.loadmat('X.mat')
InputImage1 = matcontent['XX']
