Tried to get working the Deeplearning Script - only successful in small parts:
Installation: win 10, zorro 2.56, R 4.3.2, Python (version 3.11.5 or 6) within R, as alternative as system installation or Anaconda3, Keras always as R package (version 2.13), Caret, Deepnet
My Experience:
- Got working Deepnet from inside R ("neural.test()") and from Zorro as expected. Had to move set.seed() from neural.init() to neural.train() to get identical results from one to multicore training.
- Keras/Tensorflow runs within R using neural.train(). Set.seed() same as above. Had to change predict_proba() to predict(), function was removed in Keras version2.6. No chance to get it working from Zorro, used some sink() calls in neural.save(). Looks like function call Rx( neural.save....) does not start. R is still running. No idea what is wrong, does neural.train() not return properly?
- Installing MxNet impossible, URL does not exist anymore. Project has "retired"..... when you are searching for information of this project.
Due to the fact, that deepnet is limited to 3 layers (known issue, no change since years - no maintenance), MxNet not existing anymore at least for R, i would like to get working Keras/Tensorflow. In the forum i could see some comments about this problem (Keras), but no clear advise how to overcome the problem. Is it a problem of my software installation or has Keras changed so much, that the script does not work anymore (in contradiction to the working neural.test()). Is there an interference between Keras and the R-Bridge?
So any comment would be appreciated.
