Matconvnet在尝试进行旁路时显示错误

我正在尝试使用parapooling在matconvnet中运行mnist示例。我已拨出2个GPU，但它表明这个错误试图运行cnn_mnist_experiments：Matconvnet在尝试进行旁路时显示错误

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

Error in cnn_train (line 157)

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

显然，工人无法获得访问“vl_cudatool”文件。这里可能是什么问题？

未定义的函数'vl_cudatool'用于'single'类型的输入参数。

这意味着你的vl_cudatool功能是不是在你的路径

尝试

which vl_cudatool

我不知道vl_cudatool是什么。也许你可以尝试一些较早版本的MatConvNet？

我试过了，但显示'找不到'。我甚至在matconvnet的github存储库中查看了这个函数，但它不能用作.m文件。 – tdr
