[Taichi] version 0.5.14, supported archs: [cpu, metal], commit 9a3bb30b, python 3.7.7
Traceback (most recent call last):

    ti.init(arch=ti.gpu)
AttributeError: module 'taichi' has no attribute 'gpu'

How do I troubleshoot this?

[archibate]

For now please use ti.metal instead of ti.gpu. Sorry about the confuse!

Recently we added the ti.gpu feature (#843) and updated documentions for that feature. However, we haven't released that yet (will be soon in v0.5.15).
@yuanming-hu Maybe we should update taichi.readthedocs.io only after release? So that users won't get confused by not-released-yet features.

Do you guys have a stable branch that excludes unreleased features?

[archibate]

No, we don't have a stable branch yet. Thanks for the idea! Currently master serves as the developing branch. And we use tags for stable release instead.

My suggestions:

1. Create a stable branch.
2. Contributor PRs compares from contributor:patch-xxx to master, squash before merge.
3. When release, make a PR compares from master to stable, squash before merge.
4. And the stable commit history should looks like:

[release] v0.5.15 (#1002)
[release] v0.5.14 (#1001)
[release] v0.5.13 (#1000)
...

Should be helpful when tracking bugs. What do you think?

Sounds great
