python - Serialize numpy arrays into an npz string? -


i'm looking way generate compressed binary string out of multiple numpy arrays different types. :d method recommended in question:

storing , loading numpy arrays files

is use following:

np.savez_compressed('file_name_here.npz', arr_a = a, arr_b = b)

but caveat need actual string directly , don't have path save to. there simple way directly generate binary string without saving disk? there kind of work around this?

you save compressed array stringio object , read back,

from cstringio import stringio import numpy np  x = np.ones(10)  f = stringio() np.savez_compressed(f, x=x) f.seek(0) out = f.read()  print(out)
