Error installing protobuf on mac.

[Mohit Jain]

Hello,

    I've been trying to install Caffe for about 5 days now and still seem to have made very less progress :( . Currently, I am stuck with this error on running the command to install protobuf. Im installing with anaconda (since hdf5 is already added to it).

brew install --build-from-source --with-python --fresh -vd protobuf

The installation fails here with the error message 'failed to execute: python'.

Im really struggling to get Caffe running on my Mac OS X 10.10.2. Any help in this regard would be highly appreciated.

Same error here. Did you solved it?

[Mohit Jain]

Yes. I couldn't sideline my exact problem, however, I wrote a small blog with the step-by-step process to install caffe. Hope it helps. :)

I tried following your blog post but I'm getting the exact same error that you posted above when I try to install protobuf. How did you get around this?

[Mohit Jain]

Hi,
   As I mentioned earlier, I wasn't able to sideline the problem as such... However, A fresh start got me through. What I would suggest you do is remove all installed dependencies for this task, restart your machine and then follow the steps for installation... It might have been a problem of stray environment variables now that I think of it. Wouldn't be able to help much after that though :/ Hope you get through with this approach.

Regards,
Mohit

Thanks for the response Mohit. I will try and do a fresh install.
