I have a torch.FloatTensor that is 2 rows and 200 columns. I want to print the lines to a text file. Is there a toString() method for the torch.FloatTensor? If not, how do you print the line to the file? Thanks.

I can convert the FloatTensor into a Lua table: 

    local line = a[1]

    local table = {}
    for i=1,line:size(1) do
        table[i] = line[i]
    end

Is there an easy way to convert the Lua table to a string, so I can write it to file? Thanks!

  • There doesn't appear to be any reference to a `toString` method of any kind on what I think is the correct documentation page: https://github.com/torch/torch7/blob/master/doc/tensor.md – MTCoster Dec 08 '15 at 03:10

There is a built-in table conversion called torch.totable. If what you want to do is save and load your tensor, then it's even easier to use Torch native serialization like torch.save('file.txt', tensor, 'ascii').
