Pickle.jl

Build status codecov

An experimental package for loading and saving object in Python Pickle and Torch Pickle format.

Supports

Load

  1. basic builtin types. e.g. `Integer`, `String`, `Tuple`, `Dict`, `Vector`, `Set` ...
    julia> Pickle.load(open("test.pkl"))
    Dict{Any,Any} with 6 entries:
      "int"   => 0
      "str"   => "Julia!"
      "bytes" => UInt8[0x31, 0x32, 0x33, 0x34]
      "tuple" => (1, 2.0, "3", UInt8[0x34])
      "bool"  => true
      "float" => 3.14159
  1. some basic support of loading numpy.array and scipy.sparse.csr_matrix with Pickle.npyload("data.pkl").

  2. framework for easily analyze and implement required translation methods. For those data which are not able to restore directly will be stored in a Defer object which is similar to Expr but is mutable.

julia> load("test/test_pkl/test-np.pkl")
Defer(:build, Defer(:reduce, Defer(:numpy.core.multiarray._reconstruct), Defer(:numpy.ndarray), (0,), UInt8[0x62]),
 (1, (3, 5), Defer(:build, Defer(:reduce, Defer(:numpy.dtype), f8, 0, 1), (3, "<", nothing, nothing, nothing, -1, -
1, 0)), false, UInt8[0x29, 0x0f, 0x9c, 0x3b, 0x11, 0x5a, 0xbf, 0x3f, 0x29, 0xa6    0xb8, 0x3f, 0x6b, 0x4a, 0x31, 0
xab, 0x2b, 0xc5, 0xf2, 0x3f]))

  1. basic builtin types. e.g. `Integer`, `String`, `Tuple`, `Dict`, `Vector`, `Set` ...

Pickle.Torch

We also support loading/saving the tensor data from/for pytorch.

julia> Pickle.Torch.THsave("mydata.bin", [randn(3,5), randn(5)])

julia> Pickle.Torch.THload("mydata.bin")
2-element Array{Any,1}:
