Hi, when I try to install scs with gpu `python setup.py install --scs --gpu`, it comes with the following error: #71

What version of Cuda / CUsparse are you using? This looks like you're probably using an older version than SCS is assuming.

Thank you for your reply. My CUDA version is 10.2. And if it is a version problem, can I get an earlier version of SCS? Or can I only solve it by updating CUDA?

bodono commented 1 year ago

I'm not sure what the earliest version of CuSparse where those functions appeared, but they are in version 12.2: https://docs.nvidia.com/cuda/cusparse/

I would recommend updating CuSparse over using an old version of SCS. Alternately you can use the MKL version of SCS, which is trypically faster than the GPU version anyway.

Okay, I'll try the MKL version of SCS first, thanks again!

====================================

(GPU version) Hello, I upgraded my CUDA but this error seems to still persist and there are many "unknown type name" errors.

I'm not sure what the earliest version of CuSparse where those functions appeared, but they are in version 12.2: https://docs.nvidia.com/cuda/cusparse/

I would recommend updating CuSparse over using an old version of SCS. Alternately you can use the MKL version of SCS, which is trypically faster than the GPU version anyway.

scs-gpu version

Hello, I seem to have finally installed scs-gpu. there are some problems when using it. My test code is as follows:

import cvxpy as cp
import numpy as np

# Generate random SDP problem
n = 100
np.random.seed(1)
A = np.random.randn(n, n) 
A = 0.5 * (A + A.T)
X = cp.Variable((n, n), PSD=True)
obj = cp.Maximize(cp.trace(A @ X))
constraints = [X >= 0, cp.trace(X) == 1]
prob = cp.Problem(obj, constraints)

# Solve problem on GPU
prob.solve(solver=cp.SCS, gpu=True, use_indirect=True)

# Print solution
print("Optimal value: ", prob.value)
print("Solution: ")
print(X.value)

Due to the configuration of my computer, I can only install cuda11.8 at most, so I tested two versions of scs-gpu：3.0.0 and 3.2.0

TEST 1: version 3.0.0

And the error reported is as follows:

** On entry to cusparseCreateCsr() parameter number 5 (csrRowOffsets) had an illegal value: null pointer

 ** On entry to cusparseCreateDnVec() parameter number 3 (values) had an illegal value: null pointer

 ** On entry to cusparseCreateDnVec() parameter number 3 (values) had an illegal value: null pointer

 ** On entry to cusparseCreateDnVec() parameter number 3 (values) had an illegal value: null pointer

Segmentation fault (core dumped)

And when I run the pytest -v, it comes:
