jinfei3459 opened a new issue #14643: Check failed: inputs[i]->ctx() == default_ctx (cpu(0) vs. gpu(0)) CachedOp requires all inputs to live on the same context. But data is on gpu(0) while conv0_weight is on cpu(0) URL: https://github.com/apache/incubator-mxnet/issues/14643 ## Description (Brief description of the problem in no more than 2 sentences.) Check failed: inputs[i]->ctx() == default_ctx (cpu(0) vs. gpu(0)) CachedOp requires all inputs to live on the same context. But data is on gpu(0) while conv0_weight is on cpu(0) ``` ----------Python Info---------- Version : 3.6.5 Compiler : GCC 5.4.0 20160609 Build : ('default', 'Aug 21 2018 22:24:01') Arch : ('64bit', 'ELF') ------------Pip Info----------- Version : 19.0.3 Directory : /usr/local/lib/python3.6/site-packages/pip ----------MXNet Info----------- Version : 1.3.0 Directory : /data4/zjf/install_packs/mxnet-131/python/mxnet Hashtag not found.
