There are many ways to use CUDA to solve the inverse of a matrix. You can also write your own kernel function to implement it. I checked the CSDN Cublas’s method for solving matrix inverses, but the author’s writing is rather cumbersome, and other people who watch and learn will find it difficult to understand. […]

Matrix multiplication using cublas
Use CUDA to write a matrix multiplication C = A X B (matrix dimensions: A: M X K, B: K X N, C: M X N), of course you can write the kernel function yourself, but the efficiency is not as good The cublas algorithm that comes with CUDA is highly efficient. The only thing […]
Solve the problem of Tensorflow error (CUBLAS_STATUS_EXECUTION_FAILED) error reporting
Description of problem System: Ubuntu20.04 Graphics card: RTX A5000 Physical machine CUDA Verion: 11.4 Installed Tensorflow version: tensorflow-gpu==1.13.1 Using Conda to create a virtual environment and pull Tensorflow’s official docker image in two ways, The Conda virtual environment configuration (Python3.7.2) is installed using the conda command, as follows: cudatoolkit 10.0.130 h8c5a6a4_10 https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge cudnn 7.6.5.32 ha8d7eb6_1 […]
[Solved] Running the DeBERTa model on the GPU reports an error: RuntimeError: CUDA error: CUBLAS_STATUS_NOT_INITIALIZED when calling cublasCrea
Using the DeBERTa model to run on the GPU reports an error: RuntimeError: CUDA error: CUBLAS_STATUS_NOT_INITIALIZED when calling cublasCreate(handle) But the bert_base_chinese model can run normally. What is the reason? model.to(device) # Error reported here Show error message: RuntimeError: CUDA error: CUBLAS_STATUS_NOT_INITIALIZED when calling cublasCreate(handle) What is the reason for this? How to change it?

[Solved] RuntimeError: CUDA error: CUBLAS_STATUS_ALLOC_FAILED when calling `cublasCreate(handle)` problem solving
1. Description of the problem When using the transformers package to call the Bert pre-training model of the pytorch framework, the normal bert-base-cased is used to run normally on other datasets, but when using Roberta, it keeps reporting an error: RuntimeError: CUDA error: CUBLAS_STATUS_ALLOC_FAILED when calling `cublasCreate(handle)` I have been busy for several days and […]
