NetworkVisualizationError + ModelConstructionError (text classification)

[user3549]

Hi, I'm testing the text classification plugin in DIGITS, following this example : https://github.com/NVIDIA/DIGITS/tree/master/examples/text-classification I have these errors (using the same algorithm and data):

NetworkVisualizationError:

[user3549]

Just to confirm that I have installed all the extra dependencies, including lua-pb https://github.com/NVIDIA/DIGITS/blob/master/docs/BuildTorch.md

[aaranmcguire]

I'm also having this issue, I've installed all the dependencies I've found in documentation. Heres a Dockerfile https://gist.github.com/aaranmcguire/35b1cb4e197dc2a0c3e8262c2329453c

[aaranmcguire]

@user3549 Just found out you need to re-install nn (luarocks install nn) - It seems the version installed by Torch does not have the nn.OneHot module.

[user3549]

@aaranmcguire Thanks! I re-installed nn and dpnn and still have the same error:

[user3549]

@lukeyeager Do you have any clues to solve this error? Thanks!

[aaranmcguire]

@user3549 Can you post the whole error?

[user3549]

@aaranmcguire It's the same error that I mentioned above. The error occurs when I run the construction of the model, following this example : https://github.com/NVIDIA/DIGITS/tree/master/examples/text-classification. Here is the whole error again: Train Torch Model Error Initialized at 11:03:53 AM (1 second) Running at 11:03:54 AM (0 seconds) Error at 11:03:55 AM (Total - 2 seconds) ERROR: torch-new/install/share/lua/5.2/threads/threads.lua:183: [thread 3 callback] torch-new/install/share/lua/5.2/pb/standard/buffer.lua:40: attempt to call global 'module' (a nil value) Last output: torch-new/install/share/lua/5.2/threads/threads.lua:183: [thread 3 callback] torch-new/install/share/lua/5.2/pb/standard/buffer.lua:40: attempt to call global 'module' (a nil value)

[aaranmcguire]

@user3549 You may need to check the output from the console as I don't think this is the whole error message. Also, are you running this in docker?

[user3549]

No, I'm not using docker. The output from the console is what I put in my first message, here is the error again:

[user3549]

@aaranmcguire I guess there is no solution to fix the error?

[augustoicaro]

@user3549 Same problem here after follow all steps to build and configure torch. Do you solve this?

[evertonaleixo]

I am having the same problemen.

Someone find the solution?
