ERROR: TypeError: read_refs: in typeassert, expected Array{Array{T,N},1}, got Array{Array{T,N},1} #229

I'm getting an error loading a saved snapshot.I believe it is from the compose package.

Thanks for your help

I have the same error. Wondering if you found a solution.

DilumAluthge commented 7 years ago

I am also getting the same error when trying to load a snapshot. It seems like the same error as #219.

This post on Discourse also seems to be the same error: https://discourse.julialang.org/t/mocha-type-assert-failure/3189

I haven't been able to find a solution. @pluskid do you have any ideas?

DilumAluthge commented 7 years ago

Hi all - I think I have a fix for this. Please see this pull request: https://github.com/JuliaIO/JLD.jl/pull/170

DilumAluthge commented 7 years ago

Until the pull request is reviewed, you can implement the fix on your machine as follows:

  1. Go to the "src" directory within the JLD package directory in your Julia install. The path is probably something like $HOME/.julia/v0.x/JLD/src. (For example, for me, the directory was located at "/Users/dilum/.julia/v0.5/JLD/src")
  2. In the "src" directory, open the "JLD.jl" file in your favorite text editor.
  3. Find the read_refs function. It should start on or near line 473.
  4. Find the line that reads out = Array{T}(dims). It should be on or near line 478.
  5. Change that line to instead read out = Array{Any}(dims).
  6. Save and close "JLD.jl"

You will need to quit any existing Julia sessions.
