Segmentation fault on python 3.8 following instruction from acme #51

Closed MichelangeloConserva closed 3 years ago

MichelangeloConserva commented 3 years ago

Hello all,

I am trying to install dm-acme on python 3.8.

Following the instructions on the GitHub page, I installed

pip install dm-acme
pip install dm-acme[reverb]
pip install dm-acme[tf]

However I am getting a segmentation fault error when importing reverb.

python3.8 crashed with SIGSEGV in tensorflow::OpDefBuilder::~OpDefBuilder()

I am using the following package versions:

dm_acme-0.2.1-py3-none-any.whl
dm_reverb_nightly-0.3.0.dev20210617-cp38-cp38-manylinux2010_x86_64.whl
tfp_nightly-0.14.0.dev20210618-py2.py3-none-any.whl
tf_nightly-2.6.0.dev20210618-cp38-cp38-manylinux2010_x86_64.whl
tensorflow_metadata-1.0.0-py3-none-any.whl

Do you have any idea of the source of the issue? Thanks.

Kind regards, Michelangelo

Hi! This issue is due to the mismatch between tf and reverb versions (see that reverb uses a nightly from the 17th and tf from the 18th), which itself is due to a problem with the reverb nightly being pushed on the 18th. This should be working now as all of the nightlies are updated to the 19th.

In some sense, though, this is more of an Acme problem and on github that's been addressed with a quickfix in the form of https://github.com/deepmind/acme/commit/c7d3970d898c7b01be19d570a2740520984bc2e3 (and we'll roll out a better fix shortly).
