Unable to save Lorenzdata in example_script_CPUmethod #30

Closed jpainam closed 5 years ago

jpainam commented 5 years ago

Hi, I'm trying to run the code in example_script_CPUmethod.m but end up with this error.

Error using save
Unable to write file results\Lorenzdata_1->2__RAG4_TGA_opt_us_TEpermtest_output.mat: Invalid argument.

I tried to change the directory, but it still doesn't work.

Thank you

Hi @jpainam, could you post the save command you are using? Do you provide the file name with or without the '.mat' extension? This could be an issue, see for example here.

Hi, removing these special characters 1->2__ from the filename solved the problem. But now I have another problem. TRENTOOL ERROR: You requested ensemble method with GPU calculation. No Nvidia GPU could be detected on your system. How can I avoid using my GPU? I'm running example_script_ensemblemethod.m I'm using Windows.

Hi Jean-Paul,

to avoid using the GPU you would have to shift from the ensemble method to the older standard method. This is because the computations of the ensemble method are so demanding that execution on CPU will potentially have to wait for a very long time, hence they were not implemented. However, we strongly recommend to use the ensemble method as it makes better use of the data.

If you're familiar with python you may want to have a look at IDTxl (https://github.com/pwollstadt/IDTxl, which is sort of a spiritual successor to trentool), there the ensemble method would be available as a CPU-based version, and also as an OpenCL version for AMD or NVIDIA GPUs.

Best,

Michael

Thanks @mwibral I'll try https://github.com/pwollstadt/IDTxl as I'm already familiar with python.
