not seeing plot when i execute model.plot() #5

Open Mawul4j opened 8 years ago

Mawul4j commented 8 years ago

I would like to reproduce the results in figure 4 of the paper "Nested Variational Compression in Deep Gaussian Processes" from "Nested Deep GPs.ipynb" notebook but model.plot() does not show any figure. Please what am i doing wrong?

@mzwiessele is this associated with the changes of the plotting code for GPy?

Could you provide a code snippet reproducing the error and your python version, so we can narrow it down? Also which GPy are you using?

Please, is there anything i am doing wrong?

Mawul4j commented 8 years ago

I have managed to upgrade GPy to version 0.9.4 but this issue persists. Follow up: Is there any solution to this?

mzwiessele commented 8 years ago

I don't think it has anything to do with you doing something wrong. I cannot be sure though. Could you give us a minimalist example of when it goes wrong? So we can run it on newer versions of GPy and see how it performs there? Also we might be able to find the problem, if there is one in DeepGP.

Thanks

Okay. when i execute "model.plot()", basically it shows nothing Also when i execute for layer in model.layers: ----> layer.plot() ValueError: x and y must have same first dimension

I don't know if that makes sense.

mzwiessele commented 8 years ago

Do you have a piece of code, which we can run, which reproduces the error? That would be very helpful in order to see where the problem lies.

Thanks

Have you tried commenting out this? https://github.com/SheffieldML/deepGPy/blob/master/step_fn_demo.py#L4

Mawul4j commented 8 years ago

Yes but it did not solve the problem for me. Did it work for you?

thangbui commented 8 years ago

OK nevermind my previous comment as you were trying to run the notebook, not the step function demo script.

I couldn't replicate the problem you have on a mac with the latest GPy.

Mawul4j commented 8 years ago

The plotting.py file contains code that only covers cases where input and output dimensions are ==1. Could it be that the complete plotting.py file has not been uploaded here on github?

No, if it works for Thang, it's on github.

If your output dimension is larger than 1, I suspect that simply no plot will appear.

@jameshensman Basically, i want to reproduce figure 4 of the paper "Nested Variational Compression in Deep Gaussian Processes". So, I ran the example in the notebook on robot wireless data to get that result. Maybe i am doing this wrong, but can you please show me how figure 4 of that paper was produced with DeepGPy? I believe Thang was helping with the step function demo.
