Error in method definition: function Base.sub2ind must be explicated imported

New to Julia

Goode evening
I’m not familiar with Julia programming and I’m trying to run the code below that was made on Julia 0.4.5. I got two errors messages. I’m working on Julia 0.6.4 - Atom 1.29> I suppose I have to import something but I don’t know how the syntax should be. Can Somebody help?

Error in method definition: function Base.sub2ind must be explicited imported to be extended
Error in method definition: function Base.ind2sub must be explicited imported to be extended

unction sub2ind(feat_size,feat_ind)

#================================================================
Get the single index corresponding to the feature indices given
================================================================#

total_feat = length(feat_ind)

index = 0

for i in range(1,total_feat)
    if i < total_feat
        index = index +  (feat_ind[i]-1) * prod(feat_size[i+1:end])
    else
        index = index + (feat_ind[i]-1)
    end
end

return (index+1)

end

function ind2sub(feat_size,index)

#================================================================
Get the feature indices corresponding to the given index
================================================================#

last = length(feat_size);

subscripts = zeros(Int,length(feat_size))

index = index - 1

while last>=1
    subscripts[last]   = (index % feat_size[last]) + 1
    index              = floor(Int,index / feat_size[last])
    last               = last - 1;
end

return subscripts

end

import Base: sub2ind, ind2sub

Please quote your code and copy and paste full error messages precisely.

Thanks. It works, but I got a new different error when I execute the script Run.jl

Here is the code of script Run.jl

Backticks (`, just to the left of the ‘1’ key on most keyboards) are different from single quotes ('). Please use backticks to quote your code as described in this post and check the result in the preview window.

Is it ok ?

No. You’re using backticks now, which is good, but not in the right way. See this post (again) for what it should look like and how to do it.

I think, I finally understood. Can somebody help to fix the error in the code above. The error is:
UndefVarErrror: save not defined

Probably missing using FileIO? See https://github.com/simonster/JLD2.jl/tree/v0.0.6#save-and-load-functions.
