Reading .npz files from R

Question

I save .npz files from Python and wanna read it in R.

I tried using npyLoad function but i get this error

library(RcppCNPy)
Data <- npyLoad("xx.npz")

Error in npyLoad("xx.npz") : header ended improperly

I think this happens because i saved my data from Python in Data array but i can't specify this in npyLoad.

So, is there away to read this compressed npy files in R. ?

See the [existing issue ticket at GitHub](https://github.com/eddelbuettel/rcppcnpy/issues/8); someone needs to implement it. I never needed it, so it is not part of my package (yet). CNPy supports it... — Dirk Eddelbuettel, Dec 28 '17 at 16:22

As the saying goes in Open Souce land: if you are the one with the itch, maybe you should be the one writing this (or fund someone writing it for you). — Dirk Eddelbuettel, Dec 28 '17 at 16:45

The issue linked by Dirk has a new comment that explains a workaround. The main idea is to use the reticulate package to access the numpy functionality.

library(reticulate)
np <- import("numpy")

npz1 <- np$load("foo1.npz")
npz1$files
npz1$f[["arr_0"]]
npz1$f[["arr_1"]]
