lmdb creation: Input/output error

[p.Paul]

I am trying to create lmdb for images and labels. I met with this problem and I am stuck. Could any one please help me? This one was working before.

lmdb.Error: ../data/HPElmdb/image-lmdb_train: Input/output error

     images_db = lmdb.open(images_file, map_size=int(1e12), map_async=True, writemap=True)

You might have created a lmdb directory in previous instance inside the directory where you are storing your training images. Deleting lmdb directory might work.

Thank you for your reply. But that is not the case. I have deleted all the folders,. but still showing this error! Is it something related to memory?

[p.Paul]

Is there anyone who ca help me?
I have enough memory. It was working already once. But I have some erros with manipulating numpy arrays, and with no change on the code , I got this  error. This is why I think its a memoryproblem. But cant figure it out!

I trie to run MNIST example, http://caffe.berkeleyvision.org/gathered/examples/mnist.html
So, even this is not working

 ./examples/mnist/create_mnist.sh

Hi Could you solve this??
even I facing this issue but with a different error. build/examples/mnist/convert_mnist_data.bin: Syntax error: word unexpected (expecting ")")

I could find a work around for this. I was getting the above error when I was using caffe_android_lib repo. I was using that repo as I was porting caffe on mobile. Hence the architecture was ARM.
Later , I have cloned just the caffe repo(BVLC/caffe and not android_caffe_lib), built it though could not built is fully, but managed to get tools directly built.
Then I had executed these commands. It worked fine. This says, the below scripts are compatible with only x86 architecture.
cd $CAFFE_ROOT
 ./data/mnist/get_mnist.sh
 ./examples/mnist/create_mnist.sh

No I could not fix it yet. For me wasnt a syntax error, but  I think a memory error! Now is that my server is hanged !
