P.S. I'm running the script like this:
Rscript -e 'library(rmarkdown); setwd("/the/path"); rmarkdown::render("CNNGWPBOQTLMAS2010.R", "html_document")'
Do you have access to an earlier version of R, for example 3.6? The problem seems to be with the Gaussian process in the Bayesian optimization package. I have not tried the code in R 4.0.

Hi Patrik,
Thanks for the reply. I tried running with R 3.6.1 and ran into the exact same issue.

I cannot find the GPfit package in your output. Try to uninstall rBayesianOptimization, then install GPfit and after that rBayesianOptimization. Run the script using only Rscript so you can see what the output is.

I couldn't find any reference to the GPfit package in the CNNGWPBOQTLMAS2010.R script, so I didn't install it myself. The script only loads two packages: keras and rBayesianOptimization. Should GPfit have been installed and loaded automatically? Is it a dependency of rBayesianOptimization?
Regardless, I've done as you suggested: uninstalled rBayesianOptimization, installed GPfit and reinstalled rBayesianOptimization, after which I ran the script directly via Rscript.
Is there a way to disable the TensorFlow warnings? Here's the output before the error occurs:

Yes, rBayesianOptimization depends on GPfit. Do you have all the output, it seems as if the MSE goes to infinity at some point.

They are.

Very strange, it runs fine for me. I think you need to run parts of the code to find where the error is. Start with loading the data and running the cnngwp function with the optimal values from the paper to see what that outputs. You can change to verbose=1 under #Fit model.

Are you running things on Linux or Windows?
Could you share the output of devtools::session_info()
?
I'm using RStudio with R3.6.1 on Ubuntu 19.10. Otherwise the same setup as you use, but I run the script via RStudio. My guess is that the data is not in the correct format in your case.

Alright. I'll have a go at debugging this within the following days and post here about any progress.
Thanks a lot for your help so far.
I tried running the script on Windows 10, from RStudio. The outcome was the same, the MSE becomes -Inf after the first epoch:
elapsed = 340.00 Round = 1 filter = 71.0000 kernel = 16.0000 lambda = 0.2281 Value = -Inf
elapsed = 283.06 Round = 2 filter = 60.0000 kernel = 11.0000 lambda = 0.3123 Value = -Inf
elapsed = 374.09 Round = 3 filter = 90.0000 kernel = 18.0000 lambda = 0.2075 Value = -Inf
elapsed = 194.56 Round = 4 filter = 29.0000 kernel = 28.0000 lambda = 0.1620 Value = -Inf
I'm quite new to DL in general. It would help a lot if you could be more specific about what you meant in your previous message:
Start with loading the data and running
the cnngwp function with the optimal values from the paper to see what that
outputs. You can change to verbose=1 under #Fit model.
Do you also get those TF warning messages and do you know of any way to get rid of them? Lots of these are printed and it makes it difficult to track the actual useful output.
WARNING:tensorflow:Can save best model only with val_mean_squared_error available, skipping.
WARNING:tensorflow:Can save best model only with val_mean_squared_error available, skipping.
I found a seemingly related issue, where someone mentioned that the warnings could be caused by having multiple outputs https://stackoverflow.com/questions/46438247/unable-to-save-weights-while-using-pre-trained-vgg16-model.

By this I mean that you should run the code line by line instead of the whole script and look at the output. The cnngwp function needs three input values. For example cnngwp(64,27,0.571).

It looks like the main problem comes from the following line:
MSEmin <- min(history$metrics$val_mean_squared_error)
The history
list doesn't contain an element called val_mean_squared_error
. This results in MSEmin getting the value Inf
:
> min(history$metrics$val_mean_squared_error)
[1] Inf
Warning message:
In min(history$metrics$val_mean_squared_error) :
no non-missing arguments to min; returning Inf
In my case, this is the structure of the list history$metrics
:
> names(history$metrics)
[1] "loss" "mse" "val_loss" "val_mse"
I solved the main issue by replacing:
MSEmin <- min(history$metrics$val_mean_squared_error)
with:
MSEmin <- min(history$metrics$val_mse)
It looks like the TensorFlow warnings were related to this, as well, as they also mentioned missing val_mean_squared_error
values. I got rid of them by changing the line:
monitor = "val_mean_squared_error",
to:
monitor = "val_mse",
in the cp_callback
creation code.
I'm not sure why the history
object contains val_mse
instead of val_mean_squared_error
elements, as it seemed to be expected in the code.
In the end, this was the final output for me, which is quite similar to the optimal values mentioned in the article (interestingly, the kernel value was the exactly the same):
Best Parameters Found:
Round = 15 filter = 80.0000 kernel = 27.0000 lambda = 0.6729 Value = -62.7409
The final MSE was only slightly worse compared to the one from the article: 62.74 vs. 62.34, respectively.
Should I submit a pull request for the modifications mentioned above?
Great that you found the problem. It is strange that it works for me. I will add a comment in the code, you don't need a pull request at this stage. In the paper, I repeated the BO 25 times and averaged over the three parameters (filter, kernel and lambda) to get modelaveraged(MA) estimates. Then I ran only the cnngwp function with these MA estimates, changing the code under #Prediction of yhat based on the best model. One should repeat this procedure also, lets say 25 times, and average over yhat. This will result in ensemble test predictions that further will decrease test MSE. The BO MA and ensemble prediction is imoprtant to stabilize and decrease test MSE.

It looks like the main problem comes from the following line:
MSEmin <- min(history$metrics$val_mean_squared_error)
The history list doesn't contain an element called val_mean_squared_error. This results in MSEmin getting the value Inf:
min(history$metrics$val_mean_squared_error) [1] Inf Warning message: In min(history$metrics$val_mean_squared_error) : no non-missing arguments to min; returning Inf
In my case, this is the structure of the list history$metrics:
names(history$metrics) [1] "loss" "mse" "val_loss" "val_mse"
I solved the main issue by replacing:
MSEmin <- min(history$metrics$val_mean_squared_error)
with:
MSEmin <- min(history$metrics$val_mse)
It looks like the TensorFlow warnings were related to this, as well, as they also mentioned missing val_mean_squared_error values. I got rid of them by changing the line:
monitor = "val_mean_squared_error",
to:
monitor = "val_mse",
in the cp_callback creation code.
I'm not sure why the history object contains val_mse instead of val_mean_squared_error elements, as it seemed to be expected in the code.

Alright. Thanks a lot for all this information and for your help.
Hello,
I am attempting to reproduce the simulated data example from https://doi.org/10.3389/fgene.2020.00025 using the script from this repository. However, I'm running into an error:
Any advice for how to deal with this would be much appreciated.
My R session is as follows:
