Kenneth-X opened a new issue #9344: fcn-xs for mutil GPU URL: https://github.com/apache/incubator-mxnet/issues/9344 i follow the code: _python -u fcn_xs.py --model=fcn32s --prefix=VGG_FC_ILSVRC_16_layers --epoch=74 --init-type=vgg16_ and change: _ctx = [mx.gpu(0),mx.gpu(1),mx.gpu(2),mx.gpu(3)]_ in 'fcn_x.py' file but i get the error: **File "/data-sdc/tao.xie/mxnet/python/mxnet/base.py", line 146, in check_call raise MXNetError(py_str(_LIB.MXGetLastError())) mxnet.base.MXNetError: [13:50:42] include/mxnet/./base.h:341: Invalid context string [gpu(0), gpu(1), gpu(2),gpu(3)]** then i debug it and find: in 'init_fcnxs.py' file the function' init_from_vgg16' def init_from_vgg16(ctx, fcnxs_symbol, vgg16fc_args, vgg16fc_auxs): fcnxs_args = vgg16fc_args.copy() fcnxs_auxs = vgg16fc_auxs.copy() for k,v in fcnxs_args.items(): if(v.context != ctx): **fcnxs_args[k] = mx.nd.zeros(v.shape, ctx)** it gets error in 'mx.nd.zeros(v.shape, ctx)', in which 'ctx = [mx.gpu(0),mx.gpu(1),mx.gpu(2),mx.gpu(3)] ' it seems the ctx is Invalid ................ how can i change it to train using mutil gpu? need help?please
