The interface to spiceypy.libspice.dafac_c does not work for me (Ubuntu). This also may be a problem with some other SPICE toolkit routines that pass a single pointer to multiple strings, where the strings are embedded on the left edge of a 2-dimensional array of SpiceChars that is passed as a single block.

It's not urgent; I may fix it myself and issue a pull request.

This is what I do (cmnts is a list of items):

  ### Write DAF comments
  nComments = len(cmnts)
  lenvals = max([nComments for cmnt in cmnts]) + 1

  try:  sp.dafac_c(handle,nComments,lenvals,cmnts)
  except:
    ### As of October, 2017, spiceypy.dafac_c does not work
    ### - build string and call sp.libspice.dafac_c directly
    arr = ''.join([(cmnt + ('\0'*lenvals))[:lenvals] for cmnt in cmnts])
    sp.libspice.dafac_c(handle,nComments,lenvals,arr)

P.S. Andrew, I see you coded the HapkeModel; I met him once, I think it was in AZ. I also coded the model in gawk.

This comes from C of course but is very un-pythonic.
See for example for getfov:

http://naif.jpl.nasa.gov/pub/naif/toolkit_docs/C/cspice/getfov_c.html

the required inputs are 4:

   VARIABLE  I/O  DESCRIPTION 
   --------  ---  -------------------------------------------------- 
   instid     I   NAIF ID of an instrument.
   room       I   Maximum number of vectors that can be returned. 
   shapelen   I   Space available in the string `shape'.
   framelen   I   Space available in the string `frame'.
   shape      O   Instrument FOV shape. 
   frame      O   Name of the frame in which FOV vectors are defined. 
   bsight     O   Boresight vector. 
   n          O   Number of boundary vectors returned. 
   bounds     O   FOV boundary vectors. 

but shapelen and framelen are just the lengths for the strings of shape and frame in the output. This is usually not required in Python and it would be nice if the user, especially the not-C versatile user who does not understand what is going on, would not need to provide this number.
How about setting it to something large like 100 that SpiceyPy sets internally whereever such length of a string is required?
What do people think? I think, but am not sure now, that we did that at PySPICE?

So after giving it some thought, I have decided to go forward with my plan to utilize abbreviated reStructured Text formatted docstrings for SpiceyPy, instead of using the full documentation sections contained in the headers of the files. The main reasons for this are:

1. This is how most python libraries are documented and there are various PEPs about the subject.
2. It allows for a short description and a type to be conveyed quickly.
3. It is much simpler to update, and differences between the c functions and the wrapper functions can be conveyed simply.
4. It allows me to leverage the NAIF documentation available online.
5. This also allows compatibility with tools such as Sphinx which I may use later as detailed here.

I will post a PR and merge in soon the docstrings as they are currently on my local system. It will take a while to go through and update the documentation, however this should be significantly easier and faster than writing the test functions. I will also post further updates regarding documentation here.

I am trying example from http://spiceypy.readthedocs.io/en/master/exampleone.html
I downloaded necessary file 'naif0009.tls', 'cas00084.tsc', 'cpck05Mar2004.tpc', '020514_SE_SAT105.bsp',

I'm currently working my way through the tutorials but running them in SpiceyPy rather than C. Everything was working well until the remote-sensing fovint tutorial. When I run SpiceyPy.ilumin I get significantly different values to that quoted in the remote_sensing_c.txt - i.e. for the boresight:

Thank you.

we should start transitioning builds to include and build artifacts for python 3.6, now that it is available in appveyor this shouldn't be too difficult for windows.

Well this is the big one, last summer I wasn't really aware of python wheels but this looks like a great way to distribute pre-built binaries. What is even better, I have read tutorials that show how to do this with appveyor and travis, so I could potentially have artifacts built for me by those services!

I've just tried to install the latest SpiceyPy and it looks like the spiceypy/utils directory is not being copied during setup.py install, and hence imports fail on the line:

from .utils import support_types as stypes

If I copy the folder manually, all works as expected. This is on linux x64.

Should be made to work really well, possibly have setup.py execute it first. As of now it is a mess.

https://ci.appveyor.com/project/AndrewAnnex/spiceypy/build/1.1.707

looks like something strange is occurring with windows builds.

Anaconda version:

Numpy displays some odd behaviors with integers and occasionally causes segfaults. Also supporting matrices from numpy would be useful.

update spiceypy to download and utilize N66 spice. other tickets will enclose supporting new functions from N66

Investigate using numpy.vectorize of functions, likely only needed for the ones ICY has vectorized. I consider this a feature because it is additional functionality on top of the C version of spice, but brings SpiceyPy inline with ICY.

Functions like bodn2c return a tuple of (result, True) which is very un-pythonic, as if the execution did not work as expected, it should throw a catch-able exception, in my opinion.
To not have this supported means to constantly unpack the resulting tuple into something one uses and something to be thrown away, which makes for cumbersome, less readable code.
In my opinion, it would be good if that could be changed to only return the result, and if it would return False, to throw specific exceptions what went wrong.
If you give me a pointer where to attack this, I could help. I think we had this the way I suggest in our pyspice implementation, and found it very pleasant to work with, so I could look up how Roberto coded that.

Andrew,

both using the wifi connection at Flagstaff and from ESAC I was getting the following error:

_Download failed with URLError: [SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (ssl.c:645), trying again after 15 seconds!

I was trying to do it with pip. I solved the issue by cloning SpiceyPy and then downloading cspice and unzipping it in the main directory and installing it with setup.py

Might be a glitch of for networks with a certain firewall for urllib?

Cheers!

Since the change to lowercase, SpiceyPy does not work here anymore. If I install the git-hash before that change, things work fine.
Here's the errors I get, but in words: IPython still only finds SpiceyPy, not spiceypy, but it doesn't find everything, so I guess you changed it at enough places to break it, but not enough to make it work?
I guess it works at your place because you never tried a fresh install?

Hi Andrew,

Scipeypy is a great library, thanks for making it available.

So, I using your spiceypy to calculate some positions and states from 67P/C-G.
Everything runs smoothly for str2et, sce2c and spkezr until it reachs the function ckgp.
It basically returns a weird error telling me that the function is not found.

Is it this function implemented? I have version 2.0.0 and N066.
Could you help me out on this?

I thank you in advance,

Pedro H.

I don't know if this is supported, but I don't see any comment in the README.md otherwise:

Hi guys,

anyone else having trouble with this?

Has there been a change with N0065? This used to work for me...

Hello,

I've tried to follow the Cassini position example but the first call to str2et throws a SPICE (NOLEAPSECONDS) error:

SpiceyError:

Toolkit version: N0065

SPICE(NOLEAPSECONDS) --

The variable that points to the leapseconds (DELTET/DELTA_AT) could not be located in the kernel pool. It is likely that the leapseconds kernel has not been loaded via the routine FURNSH.

str2et_c --> STR2ET --> TTRANS

I find this error odd as the ste2et_c documentation doesn't list SPICE(NOLEAPSECONDS) as a possible exception. What I assume are the two other functions in the stack trace (STR2ET and TTRANS) have no documentation on the naif website. You can find my attempt at the example here. I am running 64-bit Python 3.5.2 on Windows 10 using a WinPython distribution.

Hi! I haven't tried SpiceyPy yet but I've noticed that you have a conda package in your personal channel. Would you be interested in putting this in conda-forge? It is a sort of community-blessed repository of conda packages, with automatic testing in all platforms.

https://conda-forge.org/

While we are at it, we can even provide a conda package for SPICE itself and just declare it as a dependency. I al willing to help with all of this.

Trying to pip install spiceypy, but get the following error message:

Command "python setup.py egg_info" failed with error code 1

My Python version is 3.4.4. I was running spiceypy 1.0 before, and everything worked fine.

Thanks in advance, and please let me know if additional information is required.

I do have this started on a non-committed version, but I need to work out a good organization method for the tests. Should it all be in one test file, or should we break them down by alphabetical order?

The setup.py file needs to be made to work better (yes that is vague). The install process at the moment is a bit of a mess, not conforming to standards. The cleanup function for example doesn't do anything. Also I am not sure why uninstalling with pip doesn't work... adding SpiceyPy to pip is a later goal (1.0 release).

Hi Andrew,
This is a routine documented in other implementations but not exposed in cspice:
https://naif.jpl.nasa.gov/pub/naif/toolkit_docs/FORTRAN/spicelib/ev2lin.html

My request is naive, so I am unaware of the difficulty of implementation or whether it is even possible...

             a wrapper, so there is no letter 'c' at the end of its name.
             The prototype for this routine is declared in SpiceZfc.h.
             ./
             stlabx_ ( (doublereal *) borvec, scssb+3, corvec );

and it's not currently in SpiceyPy. Could this be implemented as well?

The install instructions are maybe incomplete?

• git-cloned SpiceyPy
• copied my cspice folder from PySpice into SpiceyPy
• I followed the README.md, went into cspice/lib and did that stuff
• then I did a python setup.py install in the main folder of SpiceyPy
• then went into Test folder and tried `python exampleProgramTest.py'. This is what I got:

$ python exampleProgramTest.py

I guess I have to put the spice.so at the right place, where is that?

the NAIF just released toolkit version N65, it looks like a number of functions were added (http://naif.jpl.nasa.gov/pub/naif/toolkit/C/MacIntel_OSX_AppleC_64bit/packages/whats.new). It is a high priority to support these new functions!

I am using SpiceyPy in order to do frame transformations and use de430 for planetary ephemerids. I can install and use SpiceyPy correctly on my local machine, but I am having issues installing this on my travis-ci testing virtual machines, cf. https://travis-ci.org/ChristopherRabotin/smd/builds/207118128 . I don't think this issue is specifically related to SpiceyPy, but I was wondering whether you had encountered that error before, or whether you had any tips on fixing this?
Thanks.

Okay, I was able to run the Cassini example. However, creating a window for input to gfdist isn't obvious. Also, the c example that's the template for gfdist sends result as a pointer input. The matlab example seems more appropriate, in which result is an output. An example would be helpful. What are the plans for posting such "cookbooks" moving forward? I'd be happy to help as I'm learning this stuff.

I tried pip install spiceypy running pip from
/Users/rfrench/Library/Enthought/Canopy_64bit/User/bin/pip

I get an error that it can't find cspice.tar.Z, but I was able to follow the "Best option" URL
https://naif.jpl.nasa.gov/pub/naif/misc/toolkit_N0065/C/MacIntel_OSX_AppleC_64bit/packages/cspice.tar.Z
to get cspice on my own. However, I don't know where to install it to make pip happy.
Any suggestions?

Hi Andrew,

Is there a way to install SpiceyPy to the instance of Anaconda's Python on a Linux server instead of the default Python? I assume it involves some method of doing a manual installation where you can specify the Python path.

Thanks,
Mihir Patel

During a scheduled build, all travis linux builds failed downloading CSPICE from the naif servers returning urlexceptions of some kind (see https://travis-ci.org/AndrewAnnex/SpiceyPy/jobs/189723324)

I was unable (yet) to reproduce the failure locally or through appveyor builds (both appear normal).

Not enough information as of yet to explain issue

Hi --

Just a quick question about installation. New python user so maybe I'm doing something wrong here. I grabbed the code via git and then did python setup.py install to install it into my Anaconda / MacOS environment. After doing this, import spiceypy would not find the library.

I found that install had copied the spiceypy-1.1.0-py3.5.egg directory, but not spicepy itself. I worked around this by manually copying the spiceypy directory into site-packages, e.g.,

cp -r spiceypy /Users/throop/anaconda/envs/py3/lib/python3.5/site-packages/

Is this how it's supposed to work?

Thanks,
Henry

Andrew,

while pipping SpiceyPy from a fresh OS with a fresh Python 3 I got the following error:

Needless to say it was solved by pip installing six, but just for you to know if you want to include it as a dependency.

Hello,
I just started implementing a SPICE system in a popular 3D animation package and switched over to SpiceyPy from PySPICE, as it seems to be more active.

I've run into an issue where trying to supply a SpiceCell object to spiceypy.spkobj causes the application to crash for some reason. Probably because it expects a pointer, although to be honest I really don't know much about how the ctypes module works.

After a little investigation it looks like some functions have been modified to be more Pythonic by returning a new SpiceCell (such as bltfrm) and some haven't, such as spkobj. For that I modified wrapper.py to return a new object and it seemed to fix the crashing issue.

Is this something that should be fixed or am I using the API incorrectly somehow?
Thanks for all the hard work on this package!

Has anyone managed to multithread SpiceyPy (or Spice)? I had a quick go with the threading module but it failed miserably. Just wondering if anyone has had any success?

Please discuss work towards v1.1.0 here or in the relevant issue.

#124

I am looking for the state (position and velocity) of a minor body relative to an observatory on Earth corrected for light time aberration. The results I get with spiceypy.spkez are consistent with JPL Horizons except for the velocity of the object with respect to the observer that is off by 0.1 km/s. This is difference is likely due to having introduced an observatory defined by longitude, latitude and altitude in Horizons while spkez takes the NAIF ID 399 coresponding to Earth. Is there any way to obtain the state of a body relative to a position given in latitudinal coordinates?
