Read and write .npy and .npz files in C++. Forked from rogersce/cnpy, added an example project showing how this library can be used as a dependency. For converting .mat files to .npz and vice versa, use npy_mat_npz.
git clone https://github.com/saravanabalagi/cnpy.git
sh build.sh
For reading data:
- npy_load(f)
- npz_load(f)
- npz_load(f, var)
Once loaded into, say cnpy::NpyArray np_data variable, you can retrieve
np_data.data<T>()yields data pointerT*, where T can beint,double, etc.np_data.shapeyieldsstd::vector<size_t> shape;np_data.word_sizeyieldssize_t word_size;
For saving data:
- npy_save(f, data, shape)
- npz_save(f, var, data, shape)
example shows how to use this lib in your own projects and example.cpp has code to read and write sample numpy arrays.
