HDF5 is one answer, It’s a powerful binary data format with no upper limit on the file size

Suppose someone has sent you a HDF5 file, mytestfile,hdf5

Example_snippet/controller/utility/_datasets.js/ conda install h5py . . .

You are have the right idea, But, you don't need to loop on range(len(data

Example_snippet/controller/utility/_datasets.js/ import h5py filename = '../Res. . .
import h5py
filename = '../Results/someFileName.h5'
data = h5py.File(filename, 'r')
for group in data.keys():
   print(group)
for dset in data.[group] keys():
   print(dset)
ds_data = data[group][dset] # returns HDF5 dataset object
print(ds_data)
print(ds_data.shape, ds_data.dtype)
arr = data[group][dset][: ] # adding[: ] returns a numpy array
print(arr.shape, arr.dtype)
print(arr)
load more v
