zachgk commented on issue #15548: MXNet GPU build on CPU machine fails URL: https://github.com/apache/incubator-mxnet/issues/15548#issuecomment-521490427 @DickJC123 Can you take a look at another case of this? We run a nightly maven snapshot pipeline in the CI that builds for GPU on a CPU machine as well. However, it now seems to be failing some Scala unit tests that are run (still on the CPU machine while building for GPU). It fails either when trying to create a KVStore or use a DataIterator (MXDataIterNext). The error message it fails with is (from http://jenkins.mxnet-ci.amazon-ml.com/job/restricted-publish-artifacts/job/master/208/): ``` org.apache.mxnet.MXNetError: [20:13:12] /work/mxnet/3rdparty/dmlc-core/include/dmlc/threadediter.h:472: [20:13:12] include/mxnet/base.h:459: Check failed: e == cudaSuccess (30 vs. 0) : CUDA: unknown error Stack trace: [bt] (0) /work/mxnet/scala-package/native/target/libmxnet.so(+0x54430b) [0x7f95a73f130b] [bt] (1) /work/mxnet/scala-package/native/target/libmxnet.so(+0x2a8d4a5) [0x7f95a993a4a5] [bt] (2) /work/mxnet/scala-package/native/target/libmxnet.so(+0x346eee5) [0x7f95aa31bee5] [bt] (3) /work/mxnet/scala-package/native/target/libmxnet.so(+0x9395bd) [0x7f95a77e65bd] [bt] (4) /work/mxnet/scala-package/native/target/libmxnet.so(+0x2c63b3f) [0x7f95a9b10b3f] [bt] (5) /work/mxnet/scala-package/native/target/libmxnet.so(+0x2c0a564) [0x7f95a9ab7564] [bt] (6) /usr/lib/x86_64-linux-gnu/libstdc++.so.6(+0x91c10) [0x7f979d4e7c10] [bt] (7) /lib/x86_64-linux-gnu/libpthread.so.0(+0x8184) [0x7f979e671184] [bt] (8) /lib/x86_64-linux-gnu/libc.so.6(clone+0x6d) [0x7f979eda203d] ``` It builds MXNet using the script at https://github.com/apache/incubator-mxnet/blob/master/tools/staticbuild/build.sh and sets up cuda for building using https://github.com/apache/incubator-mxnet/blob/master/tools/setup_gpu_build_tools.sh.
