When trying to run for instance :

[https://compas-dev.github.io/main/examples/network-shortest-path.html](https://compas-dev.github.io/main/examples/network-shortest-path.html)

The error message appears: Message:

If have installed Compas through anconda and have tried the script externally on Spyder were it seems to work.

The question is: why dosen’t it work on Rhino (6.0) Python editor for me?

hi gborg,

Rhino uses IronPython. In IronPython packages such as `numpy`, `scipy`, `matplotlib` are not available. this is not a COMPAS problem but rather a limitation of IronPython itself. therefore examples that use these libraries directly will not work in Rhino. the _shortest path_ plotter is such an example.

you are not the first to be confused by this so perhaps we should point this out more explicitly in the docs.

note that COMPAS provides an RPC server and an “XFunc” object to overcome the limitations of IronPython…

best,  
tom

Hi,

I am working together with gborg.  
We tested the “XFunc” by running the given example on:

[https://compas-dev.github.io/main/api/generated/compas.utilities.XFunc.html#compas.utilities.XFunc](https://compas-dev.github.io/main/api/generated/compas.utilities.XFunc.html#compas.utilities.XFunc)

Unfortunatly we got the following error message:

Message: Traceback (most recent call last):

During handling of the above exception, another exception occurred:

ImportError:  
Importing the multiarray numpy extension module failed. Most  
likely you are trying to import a failed build of numpy.  
If you’re working with a numpy git repo, try `git clean -xdf` (removes all  
files not under version control). Otherwise reinstall numpy.

Original error was: DLL load failed: The specified module could not be found.

Traceback:  
line 410, in **call** , “C:\Users\Albin\AppData\Roaming\McNeel\Rhinoceros\6.0\Plug-ins\IronPython (814d908a-e25c-493d-97e9-ee3861957f49)\settings\lib\compas\utilities\xfunc.py”  
line 26, in , “C:\Users\Albin\Documents\master-thesis\Exempel\_Albin\xFunc\_Test.py”

It seems to be a problem with numpy. However, numpy works when running the example as gborg mentioned externally in Spyder. Running another example for rhino which does not require numpy works fine, we tested:

[https://compas-dev.github.io/main/examples/delaunay-with-boundary.html](https://compas-dev.github.io/main/examples/delaunay-with-boundary.html)

Is it because we are running Rhino 6.0 and is it possible to solve?

Best regards, Albin

hi,

can you check the version of numpy in the Anaconda Prompt?

```python
>>> import numpy
>>> numpy. __version__

```

thanks,

and maybe (for my information) the version of COMPAS, although it is unrelated…

```python

no nothing to do with Rhino.  
for whatever reason this sometimes happens…

try the following in Anaconda Prompt

```bash
conda remove numpy scipy
conda install numpy=1.16 scipy=1.2

```

by the way, when did you install COMPAS?  
was this before last week Friday?

also this from anaconda prompt:

Is it something wrong with the Paths or do I have to reinstall anaconda packages?  
Since it seems like from the log that it removed alot of packages…

can you try the following (it seems we updated the requirements of COMPAS after you installed it…)

```bash
conda create -n test python=3.7
conda activate test
conda install -c conda-forge COMPAS

```

this will create a virtual environment called `test`, activate it and install a fresh copy of Python 3.7 and COMPAS.  
with the environment active install COMPAS for Rhino

```bash
python -m compas_rhino.uninstall -v 6.0
python -m compas_rhino.install -v 6.0

```

and then test your scripts again.

the versions of `numpy` and `scipy` should be `1.16` and `1.2` or higher… well and it should work 🙂

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the multiarray numpy extension module failed. Most  
likely you are trying to import a failed build of numpy.  
Here is how to proceed:

- If you’re working with a numpy git repository, try `git clean -xdf`  
(removes all files not under version control) and rebuild numpy.
- If you are simply trying to use the numpy version that you have installed:  
your installation is broken - please reinstall numpy.
- If you have already reinstalled and that did not fix the problem, then:
  1. Check that you are using the Python you expect (you’re using C:\Users\gabri\Anaconda3\envs\test\pythonw.exe),  
and that you have no directories in your PATH or PYTHONPATH that can  
interfere with the Python and numpy versions you’re trying to use.

  2. If (1) looks fine, you can open a new issue at  
[https://github.com/numpy/numpy/issues](https://github.com/numpy/numpy/issues). Please include details on:

Original error was: DLL load failed: The specified module could not be found.

We dont really understand what the underlying problem seems to be anymore…

unfortunately it is a known problem with recent combinations of `conda` and `numpy-scipy`. we thought we had solved it with the release of last friday, but apparently that is not the case.

will get back to you when we have a solution…

could you please try the latest version of COMPAS (0.5.1) and see if that fixes your problems?

Hi @tomvanmele,

I seem to get the exact copy of this error. I’ve tried your suggestions here for fixing it, but it doesn’t seem to solve anything. As far as I can see, numPy and SciPy are correctly installed (as I can open them outside GH) and I get the same error with both XFunc and Proxy.

Anything you know that I can try?

Would be of great help!

Thanks,  
Rick

hi,

could you provide some more information?

- name of the conda environment in which you installed compas
- version of compas installed
- script that you use in GH to call numpy stuff through RPC

could you also try the following on the command line and report back?

- activate environment in which compas is installed
- launch python interpreter
- import compas
- print version

finally, can you import compas in Rhino/GH?

thanks,  
tom

Dear Tom, thanks for reacting.

I installed everything using miniconda, and installed compas in the base environment. (Compas version = 0.11.4), both Numpy and Scipy’s versions can be retrieved.

Within GH I used both Proxy and XFunc to try and get it to work:

> from compas.rpc import Proxy
> 
> with Proxy(‘compas.numerical’) as numerical:  
> …topology = numerical.topop()  
> …_pass_

or with XFunc:

> from compas.utilities import XFunc
> 
> topop = XFunc(‘compas.numerical.topop\_numpy’)  
> topology = topop()

Both give identical errors, therefore I expect numpy and/or scipy being installed wrongly.  
(e.g. compas.numerical.dr works fine!)

print version does not work in my terminal (but compas.\_\_version \_\_) gives 0.11.4

Thank you for taking time!

Rick

</div>

hi,

could you post the error?  
can you run the topop algorithm from an editor such as VS Code?

it might also be worth updating COMPAS. we have fixed many small bugs in recent releases…  
also, just as general feedback, it is a bad idea to install COMPAS (or anything else for that matter) directly into the base environment. even if you plan to have only one working environment, it is still better to create a separate environment for it…

VSCode gives an somewhat identical error, at least that NumPy and SciPy can’t be found.
