For me the notebook for macrocircuits currently crashes with:

[15] test_dm_control(env)

Traceback (most recent call last)
<ipython-input-15-04e55b918405> in <cell line: 0>()
---- > 1 test_dm_control(env)

ValueError

6 frames
/usr/local/lib/python3.11/dist-packages/acme/wrappers/single_precision.py in _convert_single_value(value)
value = np.array(value, copy=False)
if np.issubdtype(value.dtype, np.float64):
value = np.array(value, copy=False, dtype=np.float32)
elif np.issubdtype(value.dtype, np.int64):
value = np.array(value, copy=False, dtype=np.int32)

ValueError: Unable to avoid copy while creating an array as requested.
If using 'np.array(obj, copy=False)' replace it with 'np.asarray(obj)' to allow a copy when needed (no behavior change in NumPy 1.x).
For more details, see https://numpy.org/devdocs/numpy 2 0 migration_guide.html#adapting-to-changes-in-the-copy-keyword.

Which comes from the numpy 2 update, with the installed version of acme not supporting it.

I solved it by doing:

!git clone https://github.com/google-deepmind/acme.git
%cd acme/
!pip install .
%cd ..

And also installing launchpad which was not automatically installed ( using !pip install .[envs] will add its own problems so i didnt do it).

!pip install -q launchpad

Hi Yorguin,

Thanks for raising this issue and posting how you solved the problem. We are currently working on adapting the NeuroAI course for its next iteration and re-doing testing that would highlight this issue and any others. We greatly appreciate you pointing this out and mentioning how you solved the problem. This will be fixed shortly. Please let us know if anything else pops up in any other content.
