Decoded Stack trace shows that the MEX file 'caffe_.mexa64' is not found.

Line 10 of the stack trace is shown below

[ 10] 0x00007f0480c35672 mexFunction+00000336 at /root/files/fashion-detection/fast-rcnn/caffe-fast-rcnn/matlab/+caffe/private/caffe_.mexa64+210541 (file not found)

Please make sure if you have access to the mex file and it is present in the directory. If you are using a virtual machine make sure the machine has access to the location.

Follow the steps from the ’Build MatCaffe' section of the following link

http://caffe.berkeleyvision.org/tutorial/interfaces.html

Other possible workarounds are

1. If the mex file is in a git folder or network directory, remove it and place it in a separate directory on the local machine

2. Change to the directory containing the mex file using the 'cd' command in MATLAB and execute your function or script.

If MATLAB is crashing even before you could run any commands, please try the following steps

3. Remove the mex file from the MATLAB path if it exists.

You can do this by,

• Open the file \<matlabroot>\toolbox\local\pathdef.m. Here 'matlabroot' is the directory on which MATLAB is installed on your machine
• Search for the mex file 'caffe_.mexa64' and delete those lines.

4. Follow steps 1 to 3

If the issue still exists, please reach out to the author of the mex file for support. Since this is a third party mex file and is not supported by MathWorks, any further questions related to it should be directed to the author of the mex file.
