Issues

fix cadCAD for py=3.10

opened on 2023-02-15 13:45:36 by danlessa

This PR does the following:

• Remove all un-used dependencies on the repo, including funcy, which was creating an imcompatibility with Python>=3.10
• Use the Larger Than operator rather than the Equal to operator on requirements.txt in order to future-proof it

build(deps): bump wheel from 0.36.2 to 0.38.1

Release Notes

UNRELEASED

• Updated vendored packaging to 22.0

0.38.4 (2022-11-09)

• Fixed PKG-INFO conversion in bdist_wheel mangling UTF-8 header values in METADATA (PR by Anderson Bravalheri)

0.38.3 (2022-11-08)

• Fixed install failure when used with --no-binary, reported on Ubuntu 20.04, by removing setup_requires from setup.cfg

0.38.2 (2022-11-05)

• Fixed regression introduced in v0.38.1 which broke parsing of wheel file names with multiple platform tags

0.38.1 (2022-11-04)

• Removed install dependency on setuptools
• The future-proof fix in 0.36.0 for converting PyPy's SOABI into a abi tag was faulty. Fixed so that future changes in the SOABI will not change the tag.

0.38.0 (2022-10-21)

• Dropped support for Python < 3.7
• Updated vendored packaging to 21.3
• Replaced all uses of distutils with setuptools
• The handling of license_files (including glob patterns and default values) is now delegated to setuptools>=57.0.0 (#466). The package dependencies were updated to reflect this change.
• Fixed potential DoS attack via the WHEEL_INFO_RE regular expression
• Fixed ValueError: ZIP does not support timestamps before 1980 when using SOURCE_DATE_EPOCH=0 or when on-disk timestamps are earlier than 1980-01-01. Such timestamps are now changed to the minimum value before packaging.

0.37.1 (2021-12-22)

• Fixed wheel pack duplicating the WHEEL contents when the build number has changed (#415)
• Fixed parsing of file names containing commas in RECORD (PR by Hood Chatham)

0.37.0 (2021-08-09)

• Added official Python 3.10 support

cadcad 0.4.28 fails to install with python 3.10.4.

pass `params` as a dict into policy and state update functions

opened on 2022-01-21 15:14:05 by cavaunpeu

In my code, system parameters are passed (as params) into policy and state update functions as a list with a single dictionary item. For example, params might look like:

python [ { 'a': 1, 'b': 2, ... } ]

This feels unintuitive, and necessitates something like params, = params (shorthand for params = params[0]) at the top of each function.

Separately, this issue was discussed here.

This PR may fixes this issue for me, in EXEC_MODE.single_proc mode, version 0.4.28.

Before considering a merge, a discussion should be had about whether this is expected to work across the gamut of execution modes.

Unhelpful error message when mechanism does not have return signature

opened on 2021-07-28 18:07:37 by jds3d

In the case where a mechanism like:

def account_for_tax(params, step, sL, s, inputs): key = 'GRT' delegation_tokens_quantity = inputs['delegation_tokens_quantity'] delegation_tax_rate = params['delegation_tax_rate']

tax = delegation_tax_rate * delegation_tokens_quantity
value = s['GRT'] - tax
**return key, value**

does not have the bold part (return key, value), you get the following error message:

c:\Users\Josh\anaconda3\envs\py396\lib\site-packages\cadCAD\engine\simulation.py in state_update_pipeline(self, sweep_dict, simulation_list, configs, env_processes, time_step, run, additional_objs) 172 sub_step += 1 173 for [s_conf, p_conf] in configs: --> 174 states_list: List[Dict[str, Any]] = self.partial_state_update( 175 sweep_dict, sub_step, states_list, simulation_list, s_conf, p_conf, env_processes, time_step, run, 176 additional_objs c:\Users\Josh\anaconda3\envs\py396\lib\site-packages\cadCAD\engine\simulation.py in partial_state_update(self, sweep_dict, sub_step, sL, sH, state_funcs, policy_funcs, env_processes, time_step, run, additional_objs) 138 return destination 139 --> 140 last_in_copy: Dict[str, Any] = transfer_missing_fields(last_in_obj, dict(generate_record(state_funcs))) 141 last_in_copy: Dict[str, Any] = self.apply_env_proc(sweep_dict, env_processes, last_in_copy) 142 last_in_copy['substep'], last_in_copy['timestep'], last_in_copy['run'] = sub_step, time_step, run TypeError: cannot convert dictionary update sequence element #1 to a sequence

It would be more helpful to say which mechanism had the issue and what the issue was.

State Update Function PSUB key not checked

opened on 2021-03-26 06:10:31 by BenSchZA

In the following notebook, the variables dictionary keys are not checked to match against the state update function keys: https://github.com/cadCAD-org/snippets/blob/main/snippets/execution_time_decorator.ipynb

We'd expect the following code, where the key 'a' has a state update function for key 'b', to throw an error when executed by cadCAD, but no error is thrown.

python= psubs = [ { 'policies': {}, 'variables': { 'a': update_b, 'b': update_a, } } ]
