@yzhliu It should be the other way round. Let's open the CI Docker container: `docker run -it mxnetci/build.ubuntu_gpu_cu102 /bin/bash` and look at the shared libraries in `/usr/local/cuda`: ``` root@de49f0e1966c:/work/mxnet# find

If we're on a host with GPUs, we can use `docker run --gpus all -it mxnetci/build.ubuntu_gpu_cu102 /bin/bash` and the `libcuda.so` from the host as well as the host GPUs will be available inside the container. But on a CPU host this just leads to ``` docker: Error response from daemon: OCI runtime create failed: container_linux.go:349: starting container process caused "process_linux.go:449: container init caused \"process_linux.go:432: running prestart hook 0 caused \\\"error running hook: exit status 1, stdout: , stderr: nvidia-container-cli: initialization error: nvml error: driver not loaded\\\\n\\\"\"": unknown. ERRO[0000] error waiting for container: context canceled ``` The problem is that some part of the tvmop setup currenly requires `libcuda.so` to be available (it's listed as shared library dependency of some shared library that is opened). We need to check which library is introducing the dependency and consider how to fix it. Ideally there shouldn't be a dependency on `libcuda.so` as it's only available on GPU hosts. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
