kmeans's Issues

Some confusing points

Hello, thank you for your example. @bryancatanzaro @LeviBarnes
First, I ran make, and everything went well.
Then, I want to create data on CPU, so I changed your code in huge test and kmeans, I changed all device_vector parameters to pointers, and create arrays (for example, float h_data[100000];), and use cudaMemcpy to copy data from and to host and device. In order to make it simpler, I deleted most templates.
When I tried to run make, this time errors occured. I was told that many functions were defined many times, and all those functions are defined in labels.h directly. So I just conserved declarations of these functions in labels.h and moved all definitions to labels.cu. As for kernel functions prefixed by __global__, I moved all them to labels.cu and deleted declarations. Then, make was successfully run.
But , when I ran ./test, it just showed a message CUBLAS initialization failed, which is a message in struct cublas_state in labels.cu.
I don't know why these errors happened. I'm now very confusing about these. Would you please give me some hints? Thank you!
