this is the function. x is a 4 dim arrays. y is 2 dim arrays.
i want to push data with size of batchsize to data arrays.
however the error says that cget isn’t defined. so do you
know the function names that cget changed to.
```julia
function minibatch(x, y, batchsize)
data = Any[]
#for i=1:batchsize:ccount(x)-batchsize+1
for i=1:batchsize:size(x,4)-batchsize+1
j=i+batchsize-1
push!(data, (cget(x,i:j), cget(y,i:j)))
end
return data
end
```
the following is error information
```julia
ERROR: LoadError: UndefVarError: cget not defined
```

You should post a minimum working example. I tried your code with julia 0.7 and 0.6 and I got the same error that you post: cget is not defined. Clearly something is missing from your code snippet, possible import of an external package.
