When I run the code given in the document on combined aero and structure I go this error:
AttributeError: 'module' object has no attribute 'matlib'
Based on the previous answer I had got, I tried to install the updated version of 'matplotlib' , but this has not solved the problem. Any help will greatly help me as I am a FORTRAN era person and a new convert to Python.
It looks like you're trying to use an intel compiled version of python and numpy can't find an necessary underlying library. Something is messed up in your python/numpy install.
This has nothing to do with OpenAeroStruct or OpenMDAO. If you can't fix your install, I suggest trying out the Anaconda python distribution, which should have everything precompiled correctly.
I don't have enough rep to comment, but please view this answer as a comment and I'll edit it once I can answer more properly.
That sounds like a numpy installation issue. Could you please post the entire error trace that you get when you try running the command?
Additionally, what system are you on (Windows, Mac, Linux), how did you install Python, and have you tried any other Python-based code that you can get to work successfully?
Edit: the most recent version of OpenAeroStruct has been modified to avoid this issue altogether.

I am following the instructions here to install packages (I'm looking at the "Simple Installation") section: https://rstudio.github.io/reticulate/articles/python_packages.html
Here is my R code:
library(reticulate)
use_python(python="C:\\Users\\...\\AppData\\Local\\Programs\\Python\\Python39\\python.exe")
py_install("pandas")
However, I'm getting the following error:
Error: could not find a Python environment for
C:/Users/.../AppData/Local/Programs/Python/Python39/python.exe
How do I resolve this? I have used py_install() this way on another computer before, so I know it's possible and I would like to use it. However, I can't understand what I'm missing.
You might respond that I need to specify an environment when using py_install(), but the instructions in the link don't require that, and I know it can be done without specifying an environment every time. Do I need to somehow set a "default"?
EDIT: Just to clarify, I am on Windows.
You may not be connected to the proper environment. Depending on your OS, you will likely have to create a .Renviron file and direct R to look for it.
This post here, should help you diagnose the issue:

I installed Scilab 5.5.2 on Windows 10, and then installed the Scilab Code Generator toolbox.
However, when I start Scilab, the following message appears and I can't use the toolbox. This problem occurs for every toolbox.
Start Scilab Code Generator
Version: 0.9.20190122
Load macros
atomsLoad: An error occurred while loading 'xcos_code_generator-0.9.20190122':
File "C:\Users\光\AppData\Roaming\Scilab\SCILAB~1.2\atoms\x64\XCOS_C~1\09E129~1.201\macros\names" does not exist or read access denied.
(光 is my username.)
I suppose the problem comes from "\Scilab\SCILAB~1.2" in the middle of the file path. In my computer, the only folder in "Scilab" is "scilab-5.5.2", so indeed the software cannot find the file it's looking for.
Does anyone have any ideas?
I need to use the toolbox at work soon, so any help is greatly appreciated. Thank you in advance.
Note: I'm not using the latest Scilab 6.0.2 because it fails to work on my computer. It closes immediately after I open it.
I solved the problem by myself.
It was my user name "光" that caused the problem. I found people saying that user names in full-width characters such as Japanese sometimes cause problems like this.
The solution is to create another user account with a name in half-width characters and install Scilab in that account. (Just changing the full-width user name doesn't work because it doesn't change the filenames that already exist.)
I couldn't find the solution until today because I was searching for solutions only in the context of Scilab, not in the context of software in general.
I hope this answer helps someone.
I'm not sure why you are using an outdated version of Scilab. The latest version is 6.0.2 on Windows. If the newer version doesn't work properly then that's the problem you need to fix first. To test your Scilab installation you may run it in the terminal. Find the installation folder. For me, it is C:\Program Files\scilab-6.0.2\bin the on cmd go to the path and run Scilex.exe. If not uninstall everything and install it in a proper way. My recommendation is to uninstall the old Scilab you already have. Then:
Install Chocolatey package manager
Open PowerShell as Admin and run choco update all -y, once in a while update your packages this way.
run choco install Scilab -y
then open the Scilab software
run the atomsInstall("xcos_code_generator") in the console
runt the atomsLoad("xcos_code_generator") to make sure your package is installed properly. You should see this as a result:
--> atomsInstall("xcos_code_generator")

First of all, I am working on a Mac. I am trying to install Blotter from GitHub. I found several descriptions of how to do that but my RStudio tells me that I am missing Building tools and gives me a link (https://www.cnet.com/how-to/install-command-line-developer-tools-in-os-x/) where it is described to do that. So far so good. I downloaded Xcode and the command line tools for Mac and installed those. Nothing changed even after restarting R. Then I found this https://cran.r-project.org/bin/macosx/tools/. I installed it and during that, it told me that I had to do the following
"This package will install clang 6.0.0 for OS X 10.11 (El Capitan) or higher with OpenMP support in /usr/local/clang6
In order to use this compiler you have to add /usr/local/clang6/bin to the PATH environment variable such as
export PATH=/usr/local/clang6/bin:$PATH"
So I changed the environmental variable path as follows http://blog.tonytsai.name/blog/2018-05-07-setting-path-variable-for-gs-command-in-rstudio/.
How I changed the PATH variable.
Again I restarted R but still, nothing changed. I still get the notice that the building tool is missing.
Somehow it seems to me that I installed everything correctly but R doesn't recognize the Programmes. Does anyone have an idea? I tried to search for settings to tell R that I installed the command line tool but couldn't really find anything helpful.
Ok, a bit of an update.
Best I can see it that Blotter is built and stored on R-Forge packages under a package called RStrategist
In R console type/cut & paste this.
install.packages('RStrategist',repos='http://R-Forge.r-project.org')
See R forR-Forge for more details. Once this has been installed run instead.
library(RStrategist)
Unfortunately, I am not willing to install this package and see if it works mainly because 1) don't need it nor know how to use it, 2) not sure how good packages are from R-forge, though it seems legit, but, this brings me back to point one.
So before i read the updated answer of Conrad Thiele i was trying around bit. Basically i deleted R, R Studio, Xcode and Command Line tools. Then i installed Xcode, Command Line tools, R and RStudio. Then i followed the notice on https://cran.r-project.org about the tools and installed both stated tools. As mentioned in the original question the Clang package tells you to change the Environmental Variable. And there was the mistake i believe. I originally simply pasted "PATH=/usr/local/clang6/bin:$PATH" into the the ".Renviron" file. With reading up online i noticed that "export PATH=/usr/local/clang6/bin:$PATH" is actually a Command for the Mac Terminal. After executing it, it sill didn't work but then i remembered that i still had the Path "PATH=/usr/local/clang6/bin:$PATH" in the the ".Renviron" file. Once i deleted that it worked. So i guess the key was that with changing the Environmental Variable correctly R found the connection with the right tool. Patients paid off.
When I tried to use pyinstaller to package my pysnmp based code to exe file, I met the same problem as described in PyInstaller does NOT work when including Pysnmp
However, after I changed the spec file as suggested, I got another error:
Error loading Python DLL 'C:\Users\***\AppData\Local\Temp_MEI124682\python36.dll'.
LoadLibrary: The specified module could not be found.
I'm using windows 10, Python3.6.4-32bit
I'm very confused, can anybody tell me where could be the problem and how can I solve it?
Thank you in advance.
Today it finally works. I used a 32-bit python 3.6.4 before, now I downloaded a 64-bit python 3.6.4, and it works, although I don't know why. My windows is 64-bit.
in addition to coutingstar's above answer if nothing seems to work out for this issue uninstall and reinstall the version of python that matches your os version and then try the same steps.
I want to start developing of my first test addon. I have a problem on the basis of mr.bob. Any described ways have leaded to one result. my documentation
log image
Check
mrbob --help
do the same answer.
After I came to the conclusion the problem is in pre-installed Python2.7 with no worked mr.bobe and bobtemplates. I do not know how to make a working set.
Looking at your traceback I guess mr.bob is not fully supporting Windows.
The readline module on Windows is not available. There's some alternatives like pyreadline.
Seems it's a know issue: see https://github.com/domenkozar/mr.bob/issues/49
Don't know about mr.bob, but you could alternatively try adi.devgen (disclaimer: one of my add-ons). Install it with pip:
pip install adi.devgen
And then do:
devgen addOn yournamespace.youraddonname
