ghpythonremote's Issues

documentation precision: Ironpython paths

The path to use in the custom install location (doc only) should be one level deeper, in ...\settings\lib

"Location" is inside Docker container

Thank you for this nice package.
I have a quite complicated situation.
I have a docker container that contains a python venv and i want to execute commands from my Rhino python code.
Is this currently possible with this library or dou you know how to achieve this?

Furthermore, Rhino 8 is adding some newer CPython functionality do you think it is feasible to enable newer Python versions here?

Thanks!

Python 3.5/3.6

Hi,

First of all thanks for this amazing plugin!

I was wondering if you plan support for python 3 version anytime soon? It would open a lot of possibilities to certain areas.

Kind regards,
Theodore.

Python 3+ support

Hi guys,

is there a workaround in order to get python 3 support?

I'm really looking a way to connect this to tensorflow and that only runs on python 3+.

I did try a workflow with gh_cpython, that worked well with tensorflow, but then I'm missing out on sc.sticky etc.

conda:// paths do not work (conda executable not found) when conda is not installed for All Users

What it says in the title

importing methods from "ortools" library

Hi,

I'm facing an issue when trying to load a specific method from the Google "Or-Tools" library.

I have installed the library in the correct environment ("rhinoremote") and loading it from there works fine:

I can import ortools.sat.python via the sticky dictionary but can't seem to figure out how to access the cp_model method from there:

For clarity, the tree structure:

ortools__
         sat__
              python__
                       __init__.py
                       cp_model.py
                       cp_model_helper.py
                       vizualisation.py

Am i missing something obvious or is it a limitation from GhPythonRemote ?

ghPythonRemote for Python v3+ ?

Any chance an update for python3 could be available to tap into external data and use the powerful processing capacity of python, like pandas, numpy, etc and some arduino stuff?

Installation issue - Runtime error (ArgumentTypeException): expected buffer, got bytes

Hi,
Thank you for your reply on Food4Rhino.
I am trying to use python remote on Rhino 5 SR13 and GH 0.9.0076. Python 2.7 Anaconda2.
I followed the step of the installation but when I open the example file GH_python_remote and change the paths I get this error message:

rpyc error on handling string input

rpyc seems to have some problems with delivering string input, but the problem symptoms varies depending on the python packages.

All the examples below are run on a 64-bit Windows 10 machine with Rhino 6, conda env python 2.7, gh-python-remote 1.2.1.

Error script 1: numpy.fromstring

Runtime error (ImportException): No module named ghpythonremote

Hi @pilcru! Sorry to bother you, but i seem to be stuck at the installation step and really would like to try this amazing plugin.
I've followed meticulously the installation guide, but i'm also very new to all of this so i may do miss something easy.
Basically i've installed Anaconda3 (selecting "Add conda to my PATH"), created the env rhinoremote, activated it and run the provided commands.
Problems seem to happen when running the ghpyr configure ironpython installation: i've tried running the general one and the one with a specific folder, but this is what shows (in the conda prompt, win cmd prompt or powershell)

(rhinoremote) C:\Users\PREDATOR>conda env list
# conda environments:
#
base                     C:\Users\PREDATOR\anaconda3

Ancora? IronPython (814d908a-e25c-493d-97e9-ee3861957f49)\settings\lib"
The gh-python-remote package will be installed in Rhino IronPython with the command:
C:\Users\PREDATOR\anaconda3\envs\rhinoremote\python.exe -m pip install --upgrade --target=C:\Users\PREDATOR\AppData\Roaming\McNeel\Rhinoceros\7.0\Plug-ins\IronPython (814d908a-e25c-493d-97e9-ee3861957f49)\settings\lib --no-compile --ignore-requires-python gh-python-remote
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

Also i can tell you that there is no file in: "%APPDATA%\McNeel\Rhinoceros\7.0\Plug-ins^

No ghpythonremote components appear, but i can drag it on from rhinoremote env folder as well (but as you can imagine, it doesn't work and outputs: Runtime error (ImportException): No module named ghpythonremote). I've tried giving the envlist path for the location input, but also doesn't work.

I really hope i'm not wasting your time with something really silly to solve, but i can't find what i'm doing wrong.

mac osx compatibility / installation?

What are the installation steps for the Mac OSX environment (if ghpythonremote works there)? Thanks.

On MacOS, `get_python_from_path` fails -- does not follow symlinks?

Reported here https://discourse.mcneel.com/t/solve-the-error-that-gh-pythonremote-dont-work-in-mac/125455

It appears that the get_python_from_path() function does not manage to get to the proper python2.7 file from the file or folder passed as argument. Reported errors are:

“Location format for /Users/xxx/anaconda3/envs/xxxx/bin/”
did not match expected format: “method://env_name”(need more than 1 values to unpack).Falling back to getting python path from MacOS $PATH."

or

“Runtime error (RuntimeException): Remote python /Users/xxx/anaconda3/envs/xxxx/bin/python failed on launch. Does the remote python have rpyc installed?”

or

"no mudule named xxx"

Remote list-like objects do not automatically convert to GH lists

(From email)

import scriptcontext as sc
np = sc.sticky['numpy']

a = np.arange(10)
type(a.tolist())

returns <class '__builtin__.list'>, but then Grasshopper says it's a IronPython.NewTypes.System.Object, and cannot cast it to a GH list.

CPython_to_GH.py invoke Rhino 5.0 in a RH6 context

Problem

I'm trying to test the CPython_to_GH.py example with Rhino 6.0.

What happened

I installed ghpythonremote in my conda env (python2.7, activated), and the ironpython configuration seems to be set up properly, with the console telling me the following:

> python -m ghpythonremote._configure_ironpython_installation
The gh-python-remote package will be installed in Rhino IronPython with the command:
C:\Users\harry\.conda\envs\py27\python.exe -m pip install --upgrade --target=C:\Users\harry\AppData\Roaming\McNeel\Rhinoceros\6.0\Plug-ins\IronPython (814d908a-e25c-493d-97e9-ee3861957f49)\settings\lib --no-binary=:all: --no-compile --ignore-requires-python gh-python-remote
...
Successfully installed gh-python-remote-1.2.1 plumbum-1.6.7 rpyc-4.1.1
INFO:Copied example files to C:\Users\harry\AppData\Roaming\Grasshopper\UserObjects\gh-python-remote

Notice that the IronPython of Rhino 6 is correctly identified above.

But if I run python CPython_to_GH.py in the path examples, Rhino 5 will be invoked and the following error shows up:

Well, I did python -m ghpythonremote._configure_ironpython_installation 5 as well. Before I did that, the error was simply "cannot locate module ghpythonremote".

Am I doing anything wrong here? I feel like there should be a parameter in the PythonToGrasshopperRemote class to let it know that we are dealing with RH5 or RH6, if both are installed in the system.

Python to GH example does not work

(From Food4Rhino)

Rhino starts up, but shows an error message that it cannot run the python script.

Installing v1.1.1 fails when git is not installed on the path

(From email)

Trying to install v1.1.1 on a computer where git isn't installed fails:

Collecting gh-python-remote Using cached gh-python-remote-1.1.1.tar.gz DEPRECATION: Dependency Links processing has been deprecated and will be removed in a future release.

Collecting rpyc>=3.4.5 (from gh-python-remote) Cloning https://github.com/pilcru/rpyc.git (to v3.4.5) to c:\users\alex\appdata\local\temp\pip-build-tzllou\rpyc

Investigate if --process-dependency-links is still needed

This is a deprecated option already in pip v9, so getting rid of it would be great and would make updating the pip dependency safer. It seems I was only using it when installing a custom build of rpyc, so maybe it's useless now.

GH Python remote with Sympy

Hello,

I have a problem while import sympy in the GH Python through GH Python remote. The code is as below:

import rhinoscriptsyntax as rs
import scriptcontext as sc
import ghpythonremote
sp = sc.sticky['sympy']

x = sp.symbols('x')
q = sp.symbols('q', cls=Function)
Mq = sp.symbols('Mq', cls=Function)
Vq = sp.symbols('Vq', cls=Function)
diffeqbmq = Eq(Mq(x).diff(x,x), -q)
BMq = dsolve(diffeqbmq, Mq(x), ics = {Mq(0):0, Mq(l):0})
SFq = Eq(Vq(x),BMq.rhs.diff(x)) 

but the functions in Sympy such as Function, Eq, dsolve is not usable in gh python.
it shows a warning: name 'Function' is not defined.

Could I ask how to solve it?

Connecting to Python from GH does not work on IronPython 2.7.0 (Rhino version)

Using Numba

Dear @pilcru,

First let me thank you for this wonderful tool that is GHPythonRemote.

I would like to know if it is possible to use Numba with it and if so, how.
Importing it doesn't seem to be an issue but adding a @jit decorator to a function returns an error.

Example test:

nb = scriptcontext.sticky['numba']
jit = nb.jit

@jit
def f(x, y):
    return x + y

f(24, 167)

Returned error:

Provide a version string in ghpythoneremote module

That would help in debugging versions.

Long running tasks seem to time out after 30 seconds

The connection then returns with "result expired"

pip.main does not exist in pip>=10.0.0

(From Food4Rhino http://www.food4rhino.com/app/gh-python-remote#comment-27766)

This breaks the ironpython installation script. Should be easy to fix by calling subprocess instead...

Make ghpythonremote compatible with Rhino 6

This should be just a matter of changing paths, although the question remains to install for both versions if possible or only one, when running python -m ghpythonremote._configure_ironpython_installation.

Install gh-python-remote

I run into this issue while trying to install gh-python-remote.

C:\Users\mag>pip install gh-python-remote --upgrade

ERROR: No matching distribution found for gh-python-remote

What am I missing?

Thanks for your help!

Remote creation of numpy arrays is slow on large lists

(From email)

The code below takes 5-10 seconds to run, which is 5-10 seconds too many:

import scriptcontext as sc
np = sc.sticky['numpy']

np.array(range(10000))

Missing example files

The example python_to_GH.py expects a GH user component TestClusterGHPR. However, ghpythonremote._configure_ironpython_installation does not copy this file to the User Objects folder. There are also other example files which are not copied anywhere.

Runtime error (TypeErrorException): sequence item 1: expected bytes or byte array, str found

The component goes red when I run it. I get the following error message:

Connecting...
DEBUG: ghpythonremote.connectors:
Connecting. Timeout in 10 seconds.
Runtime error (TypeErrorException): sequence item 1: expected bytes or byte array, str found

Thanks for developing this tool, I have been looking for something like this for a long time!

Deal with output redirection better

Relates to #8

Write instructions to connect to a non-localhost server

Maybe even show an example to some Linux machine in the cloud, with Tensorflow. If #23 is implemented, also choose good defaults for the connection stream, based on location of the server.

Problem running example files

Running in a 2.7 environment ( conda://rhinoremote ) as directed in the guide and from a fresh anaconda3 install, I'm having problems running the GH to python remote example.

I have the following modules:

import scriptcontext as sc
scipy = sc.sticky['scipy']
numpy.linalg = sc.sticky['numpy.linalg']
numpy = sc.sticky['numpy']

I get the following error:

0. Runtime error (KeyNotFoundException): numpy
Traceback: line 3, in script

Any help/guidance would be much appreciated

thanks

"No handlers could be found for handler "GH..."" in CPython to GH context

Part of #29 seemed to be something else than just selecting a Rhino version in CPython to GH. there is also that:

there is a bug in the example you show, I'm guessing a mismatch in exception handling settings in rpyc between the two interpreters,

which also shows up in the Rhino command line in the screenshot. Investigate...

example files missing after pip install

After following the instructions:

pip install gh-python-remote --upgrade --no-binary=:all:
python -m ghpythonremote._configure_ironpython_installation

My conda console tells me:

Successfully installed gh-python-remote-1.2.1 plumbum-1.6.7 rpyc-4.1.1
...
IOError: [Errno 2] No such file or directory: 'C:\\Users\\harry\\.conda\\envs\\py27\\lib\\site-packages\\ghpythonremote\\examples\\CPython_to_GH.py'

And these are the files in my examples folder:

It's strange that this happens since we already have these example files marked as package_data in the setup.py (here). Do we need to add them in the MANIFEST.in as well?

On MacOS, the GH panel does not print the ouput string in GH_to_CPython.ghx example

Probably a Mac GH bug, but let's find a workaround.

Remote console remains empty on Windows 7

(From food4rhino)

Running ghpythonremote in windows 7, GH to Python, the console window that opens remains empty. The remote traceback is lost on errors, it is not redirected to GH.

some modules work failed -"Runtime error (SyntaxErrorException): invalid syntax"

The modules about numpy, scipy, matplotlib can work successfully in ghpython.
There will be "Runtime error (SyntaxErrorException): invalid syntax" when the module about lhsmdu imported.
The module about lhsmdu can work in vscode rhinoremote.

Update for compatibility with rpyc >= 4.1.0

#19 reports users with issues when rpyc 4.1.0 gets installed. Downgrading to 4.0.2 seems to work. It would be better to have something working with the latest from rpyc.

Delivering complex objects to the remote fails if the remote cannot unpickle them

For example, trying to deliver a (remote) numpy array. Probably this does not even make sense: we shouldn't deliver something that is already on the remote. Similarly, sending b"a" from IronPython 2 to CPython 2 won't work because it represents a call to bytes(u'a', 'latin-1') in IronPython, that CPython has no chance of understanding since bytes == str, which only takes one argument (no encoding).

But maybe this might hint at other issues when passing around netrefs or function calls.

>>> np = sc.sticky['numpy']
>>> rpyc.utils.classic.deliver(rpy, np.array(10))

Grasshopper crashes when adding time and datetime libraries

Hi, I can successfully add time and datetime to the modules, but once I try to type import the following script into my GHPython Script:
import scriptcontext time= scriptcontext.sticky['time'] datetime= scriptcontext.sticky['datetime']
The whole Rhino and Grasshopper crashes. Any idea why this would be happening? I also noticed that this happens when I try to import csv besides time and datetime. Meaning this doesn't happen when a GHPython Script only has time and datetime.

MacOS compatibility

Hello !

I read this is only compatible for Windows.
Am I right if I say making it work under MacOS is only a question of path syntax in the "helpers.py" ?

Thanks !
