eric-haibin-lin commented on issue #7034: How to switch a layer to cpu mode while the other layers are in gpu mode. URL: https://github.com/apache/incubator-mxnet/issues/7034#issuecomment-320524720 You can try the `ctx2group` option during simple_bind(). For example, if you want to specify a layer on cpu among the gpu layers, ``` a = mx.sym.var("a") b = mx.sym.var("b") with mx.AttrScope(ctx_group="cpu"): c = mx.sym.sample_negative_binomial(a,b) # runs on cpu d = mx.sym.dot(a, c) # runs on gpu executor = d.simple_bind(ctx=mx.gpu(), a=(10,), b=(10,), group2ctx={"cpu": mx.cpu()}) ``` allows `sample_negative_binomial` to be on cpu while the rest on gpu. Caveat: there's a known bug for elemwise_add with group2ctx https://github.com/apache/incubator-mxnet/issues/7080 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
