Unsupported HDF5 version

[sidec]

It seems that HDF5 version: 1.10.0 is not supported.

Is there any workaround for non-root user on Linux?

On mac right?

I'm in fact experiencing the same on arch linux (after indeed updating the hdf5 library)
To be fair due to time limitations and deadlines I just installed ubuntu on a drive and went on with that (where it still seems to work).

I have the feeling like one of the lua libraries should simply be updated (but I haven't figured out which one) (I'm very new to the lua language)

[MrKroo]

I fixed my issue on mac by installing hdf5 with homebrew and uninstalling it on MacPorts as it was using a more recent version (1.10). After this I ran the script bash install-deps and ./install.sh and everything built without error.

Some advice for Arch Linux 64bit and hdf5:

There is a package hdf5_18. I installed this package and updated torch/install/share/lua/5.1/hdf5/config.lua

 HDF5_LIBRARIES = "/usr/lib/hdf5_18/libhdf5.so"

Next problem is the assert in file.lua. fileID has the type "cdata" instead of number (because it's 64bit).
I simply changed the check in the assert.

Last problem is in group.lua. Also the groupID is an int64-cdata. It works for me, if I convert the groupID in line 37 to a number:
self._groupID = tonumber(groupID)

Thanks for that!

Please help!
I am using Mac with Yosemite 10.10.5 with CUDA 7.5 and followed ("https://www.jeffreythompson.org/blog/2016/03/25/torch-rnn-mac-install/") to install torch.
Here it states installing HDF5 using homebrew:
brew tap homebrew/science
brew install hdf5
Getting same error!

[MelomanCool]

There is a fork of torch-hdf5 that supports 1.10: https://github.com/anibali/torch-hdf5.
Also, there is a pull request for torch-rnn which uses that fork: #215

The fix is pretty simple (copied from #215's readme):

git clone https://github.com/anibali/torch-hdf5.git
cd torch-hdf5
git checkout hdf5-1.10 
luarocks make hdf5-0-0.rockspec

Alternatively to the correct solution given by @MelomanCool, you can install the correct hdf5 bindings directly via luarocks:

luarocks install https://raw.githubusercontent.com/deepmind/torch-hdf5/master/hdf5-0-0.rockspec
