On the problems of Compute_image_mean.exe in Caffe-windows

These two days have the interest to install the next caffe, feel this frame.

But in this process encountered a lot of problems, I have encountered problems and solutions to write down, easy for future generations to get started.

When the Compute_image_mean.exe is compiled, the situation occurs when the data transformation is performed.

Then, quickly go online to find relevant information.

See the following blog, about Leveldb's

http://blog.csdn.net/cywosp/article/details/20746879

There is a passage in it that says:

In version 1.15, if the Newiterator function was used to create the Leveldb::iterator object without the Delete object, the following error will be reported when the program exits:
Db/version_set.cc:806:leveldb::versionset::~versionset (): assertion ' Dummy_versions_.next_ = = &dummy_versions_ ' Failed.
Based on code analysis, the reason for the Assert failure here is primarily to prevent memory leaks.

Then, open the compiled source code (inside/tools/compute_image_mean.cpp)

Based on the blog's tips, I'll do a delete after creating the Lterator. Probably in the 70th line of the source code around the position.

    ++count;    if (count% 10000 = = 0) {      LOG (ERROR) << "processed" << count << "files.";    }  }  Delete it;  if (count% 10000! = 0) {    LOG (ERROR) << "processed" << count << "files.";  }  for (int i = 0; i < sum_blob.data_size (); ++i) {    sum_blob.set_data (i, Sum_blob.data (i)/count);  }

Modify and then compile, and then you can run through the smooth.
