train-autoencoder demo fails #4

Closed rodrigob closed 9 years ago

rodrigob commented 10 years ago

After a fresh install of torch7 and the unsup rocks, running the train-autoencoder (th train-autoencoder.lua) demonstration ends with the following error

==> constructed convolutional predictive sparse decomposition (PSD) auto-encoder
/usr/local/bin/luajit: /usr/local/share/lua/5.1/unsup/psd.lua:39: attempt to call method 'initDiagHessianParameters' (a nil value)
stack traceback:
    /usr/local/share/lua/5.1/unsup/psd.lua:39: in function 'initDiagHessianParameters'
    train-autoencoder.lua:225: in main chunk

    /usr/local/lib/luarocks/rocks/trepl/scm-1/bin/th:108: in main chunk
    [C]: at 0x00404ec4

any idea on how to fix this ?
