Error in running Compile.m #343

Closed blauyang closed 2 years ago

blauyang commented 2 years ago

Expected Behavior

By opening MATLAB on myTIGREpath/MATLAB, execute Compile.m

Actual Behavior

Run the Compile.m with the following error. I have renamed mex_CUDA_win64_MVS2015.xml to mex_CUDA_win64.xml. But I don't know why it still shows that the xml file cannot be found. I did all steps 1-6 of the installation tutorial and there were no errors.

In addition, although I downloaded cuda9.2 and ran nvcc -V in the system cmd, the cuda version is also 9.2, but when I execute gpuDevice in the matlab command window, it shows tooltik Version: 8.0 This is also a very confusing place for me, I do not know if I am really running the 9.2 version of cuda I even reset my computer system to install only 9.2 cuda, but it still shows 8.0 in matlab. problem problem2

Code to reproduce the problem (If applicable)

mex_CUDA_win64.xml not found. You may need to rename the existing files depending on your MVS version

Specifications

-MATLAB version: R2017a

When you run Compile.m, you need MATLAB to be in the TIGRE folder, i.e. in D:\Tigre\TIGRE-master\MATLAB. This is because if you are not, TIGRE/MATLAB has no way to locate that file in your computer. It just assumes it is in the current folder.

Are you running the code from there, or are you just adding all to path, then compiling from somewhere else? Looking at your MATLAB folders there, it looks like you are compiling from somewhere else.

Hi @AnderBiguri ， Wow, it worked, I should have come to ask you earlier. I also spent a day resetting my computer as well as installing various software. Thank you so much! Also can you answer my other question, I'm not sure if I'm using CUDA 9.2 or not, because the tigre toolkit requires cuda 9.2 or higher, and now my tigre is running successfully, does that mean anything?

AnderBiguri commented 2 years ago

You must be using CUDA 9.2 (newer also works, that is the minimum requirement) . Try demo 3, if that works, then you are good to go ;)

it works! thanks again!
