Error about the ctpu command to build TPU testing environment

Question

I have tried to follow the quickstart of Google TPU setup as the following link.

https://cloud.google.com/tpu/docs/quickstart

When I run "ctpu up" in the google cloud shell, it shows the following error.

*2018/08/05 09:37:08 Created TPU xxx-xxx!
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x18 pc=0x6677b3]

        /tmp/ctpu-release/src/github.com/tensorflow/tpu/tools/ctpu/main.go:87 +0xd5e*

Even I tried to ssh to the new created VM, I cannot run those sample code.

This is the first step of the setup in the above tutorial with the official google environment but it was also fail.

Would anyone can help to advise if there is any missing step?

Thanks a lot

I believe `TPU` is not available while you are running in trial mode. You may have to upgrade your project to paid one. — Asdfg, Aug 06 '18 at 17:10

This error message seems to be generated by a reference piece of code used by the TPU components to determine if the project is part of the Google organization.

Based on this, a github issue has been created to report this unexpected behavior where it is explained the following workarounds to avoid this error message:

Download the released ctpu 1.5 version from dl.google.com - Instructions displayed in github issue description.
Wait to Google Cloud Shell to auto-update to the latest version over the next week or two.

Thanks Armando, I will wait for Google Cloud Shell auto-update. — Thomas Lau, Aug 08 '18 at 04:58
