about caffe_solver.snapshot

[Hucley]

Is the function "my_solver.snapshot('snapshot_path_and_name')" to save the "XXX.caffemodel.solverstate“ file? --then we try to recover the traing proicessing by using the function"caffe_solver.restore("XXX.caffemodel.solverstate") ,but there some errors: sgd_solver.cpp:316] Check failed: state.history_size() == history_.size() (0 vs. 450) Incorrect length of history blobs. notes:in additions to this, we have not make any changes;

by reference the usage of the "caffe_solver.net{1}.save",we try "caffe_solver.net{1}.snapshot('snapshot_path_and_name')" to get the solverstate file. and another error occured:"No appropriate method, property, or field 'snapshot' for class 'caffe.Net'."
