Compile error

[syinari0123]

Thank you for this caffe2 cpp tutorial. I encountered following error when compiling this code (make).

/home/user/Desktop/caffe2_cpp_tutorial/src/caffe2/util/blob.cc: In member function ‘caffe2::TensorCPU caffe2::BlobUtil::Get()’:
/home/user/Desktop/caffe2_cpp_tutorial/src/caffe2/util/blob.cc:16:31: error: use of deleted function ‘caffe2::Tensor<Context>::Tensor(const caffe2::Tensor<Context>&) [with Context = caffe2::CPUContext]’
   return blob_.Get<TensorCPU>();
                               ^
In file included from /home/user/Desktop/caffe2_cpp_tutorial/include/caffe2/util/blob.h:5:0,

/usr/local/include/caffe2/core/tensor.h:706:3: note: declared here
   Tensor(const Tensor<Context>& src) = delete;

My environment is

• Ubuntu : 16.04
• g++ : 5.4
• Caffe2 : newest version from https://caffe2.ai/docs/getting-started.html?platform=ubuntu&configuration=compile

Do you have any idea to solve this problem?

Same problem here, any hints?

use GetMutable or blob_.Get<TensorCPU>().Clone()
