500: Internal server error , expect blob.data.ndim == 4

[jmozah]

Hi

When testing a trained model (stock AlexNet) using a single image... i get "500: internal server error", Assertion failed: expect blob.data.ndim == 4.

To clarify, you are looking at a trained model, choosing a model snapshot with epoch=x, giving either an image URL or selecting one locally, and clicking on "Test one image," right? And then you get this error?

That's strange, that shouldn't happen. I see in #10 that you may have some conflicting version of caffe on your system. Is it possible that you're linking against a different version of caffe than NVIDIA's fork? This commit is the biggest difference between NVIDIA/caffe and BVLC/caffe at the moment, and it looks like it may be related to the error that you're seeing.

Well then that's probably your problem right there. As laid out in the README, you need to use the NVIDIA/caffe fork.

@jmozah I had the same issue.
@lukeyeager I tried your solution. I had used stock caffe version with the digits so I switched to NVIDIA/caffe version and that fixed the issue.

500 ParseError 2:1 : Message type "caffe.NetParameter" has no field named "layer".

this error is also caffe version ; caffe version should nvidia/caffe fork.

@zdx3578, see my response to your issue in #39. Your problem is not related to @jmozah's.

I'm closing this issue as it seems to be fixed by building from the NVIDIA/caffe fork.
