Matconvnet在攻击parapool时显示错误

Question

我正在尝试使用parapooling在matconvnet中运行mnist示例。我分配了2个gpus，但它在尝试运行cnn_mnist_experiments时显示以下错误：

   Error using cnn_train>(spmd) (line 157)
Error detected on workers 1 2.

Error in cnn_train (line 157)
    spmd

Error in cnn_mnist (line 55)
[net, info] = trainfn(net, imdb, getBatch(opts), ...

Error in cnn_mnist_experiments (line 3)
[net_bn, info_bn] = cnn_mnist(...

Caused by:
    Error using ParameterServer/startWithMMap (line 170)
    An UndefinedFunction error was thrown on the workers for 'vl_cudatool'.  This may be because the
    file containing 'vl_cudatool' is not accessible on the workers.  Specify the required files for
    this parallel pool using the command: addAttachedFiles(pool, ...).  See the documentation for
    parpool for more details.
        Undefined function 'vl_cudatool' for input arguments of type 'single'.

显然，工作人员无法访问"vl_cudatool“文件。这里的问题可能是什么？

Answer 1

未定义的函数'vl_cudatool‘用于类型为'single’的输入参数。

这意味着您的vl_cudatool函数不在您的路径中

试一试

which vl_cudatool

我不知道vl_cudatool是什么。也许你可以试试MatConvNet的早期版本？
