Backward propagation on FraunhoferPropagator fails about hcipy HOT 10 CLOSED

Hi Emiel, I am happy to report that I successfully updated HCIPy per your instructions, and my code now works.  The bug is fixed! Thank you again for all the help and support!

Hi Emiel, Thank you very much for working on resolving this so quickly!  I did the following to install the update:>   git clone https://github.com/ehpor/hcipy

And I get the following error:"File "setup.py" not found. Directory cannot be installed in editable mode: /home/pinchen/anaconda3/lib/python3.7/site-packages/hcipy" What am I doing wrong?

You can install the fixed version from Github, see the installation page on how to do this. — You are receiving this because you were mentioned.

Hi Emiel, Is there a way to pip install a version that includes the above-referenced bug fix?  I would like to share my code with a co-worker, and it would be helpful if I can tell him to simply do something like <pip install hcipy --upgrade> to make my code run w/o error.    Thank you!Pin On Thursday, January 23, 2020, 5:47:51 PM PST, Pin Chen <[email protected]> wrote: Hi Emiel, I am happy to report that I successfully updated HCIPy per your instructions, and my code now works.  The bug is fixed!

Hi Emiel, A belated thank you, I installed v0.3.1 right away, and it works great.  -Pin On Thursday, April 2, 2020, 3:17:02 AM PDT, Emiel H.

Hi Emiel, I hope this message finds you well!  I am trying to run parallel coronagraph simulations using HCIPy and the <multiprocessing> module.  I am encountering a problem that appears to be a pickling problem; <multiprocessing> uses <pickle> to pass information among processes.  Apparently, `grid` information is lost when pickle serializes an `OpticalElement`.  Any advice/help would be much appreciated.  Here is the full trace-back:--- Traceback (most recent call last):   File "sleec_run.py", line 120, in <module>     run_emcee()   File "sleec_run.py", line 116, in run_emcee     sampler.run_mcmc(ini_positns, input_pars['nsteps'], progress=True)   File "/home/pinchen/anaconda3/envs/dev/lib/python3.8/site-packages/emcee/ensemble.py", line 384, in run_mcmc     for results in self.sample(initial_state, iterations=nsteps, **kwargs):   File "/home/pinchen/anaconda3/envs/dev/lib/python3.8/site-packages/emcee/ensemble.py", line 285, in sample     state.log_prob, state.blobs = self.compute_log_prob(state.coords)   File "/home/pinchen/anaconda3/envs/dev/lib/python3.8/site-packages/emcee/ensemble.py", line 427, in compute_log_prob     map_func(self.log_prob_fn, (p[i] for i in range(len(p))))   File "/home/pinchen/anaconda3/envs/dev/lib/python3.8/multiprocessing/pool.py", line 364, in map     return self._map_async(func, iterable, mapstar, chunksize).get()   File "/home/pinchen/anaconda3/envs/dev/lib/python3.8/multiprocessing/pool.py", line 768, in get     raise self._value   File "/home/pinchen/anaconda3/envs/dev/lib/python3.8/multiprocessing/pool.py", line 537, in _handle_tasks     put(task)   File "/home/pinchen/anaconda3/envs/dev/lib/python3.8/multiprocessing/connection.py", line 206, in send     self._send_bytes(_ForkingPickler.dumps(obj))   File "/home/pinchen/anaconda3/envs/dev/lib/python3.8/multiprocessing/reduction.py", line 51, in dumps     cls(buf, protocol).dump(obj)   File "/home/pinchen/anaconda3/envs/dev/lib/python3.8/site-packages/hcipy/optics/optical_element.py", line 713, in attribute     instance_data = self.get_instance_data(input_grid, output_grid, wavelength)   File "/home/pinchen/anaconda3/envs/dev/lib/python3.8/site-packages/hcipy/optics/optical_element.py", line 607, in get_instance_data     cache_keys = self._get_cache_keys(input_grid, output_grid, wavelength)   File "/home/pinchen/anaconda3/envs/dev/lib/python3.8/site-packages/hcipy/optics/optical_element.py", line 319, in _get_cache_keys     raise ValueError('Grid dependent, but no grids are given for lookup.')
