我正在阅读 caffe2 中的 MNIST 教程,但遇到了以下错误:
RuntimeError: [enforce fail at db.h:190] db_. Cannot open db: /home/Aakash/caffe2_notebooks/tutorial_data/mnist/mnist-train-nchw-lmdb of type lmdb Error from operator:
output: "dbreader_/home/Aakash/caffe2_notebooks/tutorial_data/mnist/mnist-train-nchw-lmdb" name: "" type: "CreateDB" arg { name: "db_type" s: "lmdb" } arg { name: "db" s: "/home/Aakash/caffe2_notebooks/tutorial_data/mnist/mnist-train-nchw-lmdb" }
为什么会这样?
