Featmap_strides is wrong and results in no performance When I used FasterRCNN to run my own data set, I found that there was almost no performance (0.8%). Later I found the reason and found that it was: In FasterRCNN, the featmap_strides of the SingleROIExtractor in the second stage is written as [8, 16, 32, 64] […]

The thread hierarchy of CUDA threads, and how a single thread threadIdx uses stride to perform skip operations and calculate multiple data at the same time
The concept of thread level: Simply put, a grid has multiple blocks, and a block has multiple threads. How big is the grid, and gridDim is used to indicate how many blocks it has, which are divided into gridDim.x, gridDim.y, and gridDim.z. How big is the block? Use blockDim to indicate how many threads it […]

[Solved] Error when deploying jit model on CPU: Could not run ‘atenempty_strided’ with arguments from the ‘CUDA’ backend
The article’s first release and subsequent updates: https://mwhls.top/3977.html, no picture/no table of contents/format error/for more information, please refer to the first article page. Check out mwhls.top for new updates. Any questions and criticisms are welcome, thank you very much! I didn’t expect that I only posted a water post yesterday because I had been pigeons […]
[Solved] Error: ValueError: At least one stride in the given numpy array is negative, and tensors with negative s
Error: ValueError: At least one stride in the given numpy array is negative, and tensors with negative strides are not currently supported. (You can probably work around this by making a copy of your array with array.copy()) The above error occurs when the data is imported, and the error code is as follows return {‘imidx’: […]

[Solved] smplx library usage error record view size is not compatible with input tensor’s size and stride
When running the code, an error occurred: there is a lot of content, but the most critical is the last two lines.
