yolov4在darknet框架下训练出现Tensor Cores are disabled until the first 3000 iterations are reached

The message "Tensor Cores are disabled until the first 3000 iterations are reached" is an informational message printed when training with YOLOv4 in the darknet framework. It is telling you that the Tensor Cores on your GPU are disabled until the first 3000 iterations of training are reached.

Tensor Cores are specialized hardware on NVIDIA GPUs that can accelerate matrix operations used in deep learning. However, in YOLOv4, Tensor Cores will only be enabled after the first 3000 iterations of training. This is because the network architecture of YOLOv4 is complex and requires a certain amount of training before Tensor Cores can be effectively utilized.

After the first 3000 iterations, Tensor Cores will be enabled, and you should see a significant increase in training speed.
