Hi,

I am getting the following error while loading the model using a checkpoint.

Any ideas on how can this error be removed?

update your torch version

Hi,

I used the following steps to install torch:
  1. git clone https://github.com/torch/distro.git ~/torch --recursive 
  2. cd ~/torch; bash install-deps;
  3. ./install.sh 
  4. source ~/.bashrc
as mentioned on the official page : http://torch.ch/docs/getting-started.html#_

I have run ./update.sh once. However, the error still persists.

How can I check if the installed version is the latest version or not?

You can search whether nn.SpatialReSampling exists in your install package. If not search google to find some other version torch have this file. https://github.com/clementfarabet/lua---nnx

Hi,

SpatialReSampling.lua and SpatialReSampling.c files exist in the following paths:
  1. /home/iab-j/torch/extra/nnx
  2. /home/iab-j/torch/install/share/lua/5.1/nnx

However, when I run the following command in torch terminal I get an error:

require 'nn' (no error, prints out all the layers)

local output = nn.SpatialReSampling{oheight=3, owidth=3}:forward(torch.Tensor(1,2,2)) (gives the following error)

[string "local output = nn.SpatialReSampling{oheight=3..."]:1: attempt to call field 'SpatialReSampling' (a nil value)
stack traceback:
[string "local output = nn.SpatialReSampling{oheight=3..."]:1: in main chunk
