Issues with Julia installation on google tpu vm

New to Julia
1

Hi,

I’m running into some issues after installing Julia 1.6.2 on a google TPU VM (just in case: a TPU VM is not the same as a TPU node). Would anyone happen to have run into this sort of issue before?

For instance, when I exit Julia, I get the following error:

julia> exit()
munmap_chunk(): invalid pointer

I get these errors both with the standard way of installing Julia described on the installation page as well as with the python helper package jill.

Info about the virtual machine, in case helpful:

I’m new to Linux and TPU VMs, so let me know if there’s info I should add that I haven’t already.

I just ran into what seems like the same issue. Have you found any solution? I posted in slack and zulip. A small thing I noticed while trying to check the glibc is that running the libx.so.6 gives a segfault, instead of displaying the usual glibc version info. Maybe google is using their own glibc?

I basically just gave up on trying to use Julia on TPU VMs (even for non-TPU-involving tasks).

Did either of you try to build julia in this environment? Do you have a working curl inside the vm?

Likewise, do you have a working git in the vm?

I’m running make right now. There’s all the usual default tools.

You may need to explicitly build libcurl and libgit2 from scratch. Consider the variables USE_BINARYBUILDER=0 or maybe USE_SYSTEM_CURL = 1.

https://github.com/conda-forge/julia-feedstock/blob/master/recipe/build.sh#L47

You can see the heavily hacked up conda-forge recipe for a lot of the options you can use.

For example, perhaps you want to USE_BINARYBUILDER_LIBGIT2 = 0 if libgit2 is specifically having issues.

Failing that, I would highly recommend a Github Issue for this kind of technical issue.
