Loading Safetensors in C++
Article summary
Quick briefing — cleaned from the original RSS feed
First, use open() to open the file and check the file size. fd = open ( path . c_str (), O_RDONLY ); file_size = lseek ( fd , 0 , SEEK_END ); To avoid loading the entire file into memory, I use mmap() to map the file into virtual memory. mapped = mmap ( nullptr , file_size , PROT_READ , MAP_PRIVATE , fd , 0 ); The first uint64_t in a safetensors file stores the header size. uint64_t header_size ; memcpy ( & header_size , mapped , sizeof ( uint64_t )); char * header_ptr = static_cast…
