The nvidia/cuda:11.8.0-base image doesn't include cuBLAS (libcublas.so.11), which KataGo requires. Instead of using the larger 'runtime' image (~1.4GB), we now copy only the required libraries from the builder: - libcublas*.so (cuBLAS for matrix operations) - libcublasLt*.so (cuBLAS LT) - libcudnn*.so (cuDNN for neural network inference) This reduces image size by ~300-500MB compared to using the runtime image. Root cause: KataGo crashed with 'libcublas.so.11: cannot open shared object file: No such file or directory'
