caffe test error no field named "net" on testing MNIST

Question

I have the same problem as Caffe error: no field named "net" on testing MNIST.

Running

keides2@ubuntu:~/caffe$ build/tools/caffe test -model examples/mnist/lenet_solver.prototxt 
                       -weights examples/mnist/lenet_iter_10000.caffemodel -iterations 100

I get the following output:

 I0820 11:31:33.820005 113569 caffe.cpp:279] Use CPU. [libprotobuf ERROR google/protobuf/text_format.cc:245] Error parsing text-format caffe.NetParameter: 2:4: Message type "caffe.NetParameter" has no field named "net".

@           0x406677  (unknown) 
@              (nil)  (unknown)

'lenet_solver.prototxt' and 'lenet_train_test.prototxt' are original (not modified).

And then,

keides2@ubuntu:~/caffe$ printenv PYTHONPATH
/home/keides2/caffe/python

Could you help me?

When running caffe test you do not need the solver file (lenet_solver.prototxt in your case), but rather use the net prototxt directly.
Try:

 build/tools/caffe test -model examples/mnist/lenet_train_test.prototxt 
                   -weights examples/mnist/lenet_iter_10000.caffemodel -iterations 100
