Problem running CRM wing case about smt HOT 17 CLOSED

It looks like there is an installation problem. How did you install SMT?

from smt.

I downloaded the files and using Anaconda environment used pip install. If there anotherway PL let me know, I will un-install and re-install. However, some of the other cases worked .

from smt.

If you have installed following the Readme here (pip install -e smt_dir) RMTB and RMTC are compiled on your machine during installation. Maybe something went wrong.

You can uninstall and then try to install from pypi directly with pip install smt.

That was exactly what I suggested. As you use Windows you can get binary distribution with:
pip install smt
Downloading the code followed by pip install -e is for development mode i.e. when you want to develop within SMT library. If you just want to use SMT, direct install from Pypi with pip install smt is simpler (and does not require compilation on Windows).

Hi,
Did as instructed (uninstalled and installed again) and ran 'testflo'. While some tests ran OK some did not go through. As before I tried running CRM wing example and got a different error. I am attaching the testflo report as well as the screen shot of error message.

Thanks for looking into my issues,

First, two remarks:

• Installation with pip install smt will work without compilation only with Python 3, but I noticed you are still using Python 2.7. In that case, it may work with a previous version of smt: pip install smt==0.2.2
• I noticed you have an smt-master directory like you downloaded a zip then install from the zip file which will fail to compile RMTB or RMTC surrogates if you do not have the right C++ compiler.

So, please just try: pip install smt==0.2.2
If it installs smt 0.2.2 successfully then you can use the code from the smt zip file you downloaded to run the crm wing example.
python examples\rans_crm_wing\run_rans_crm_wing_rmtb.py
do not execute from smt-master\smt directory, it might mess with the smt code present in the directory and smt code installed on your system.

Tried that but got this message

I was using Python 3.6 but had to change to 2.7 as a couple of other packages run only on that. Can I have both versions of python (on different drives) working in the same laptop ? if so I may do that

from smt.

You can have several installations of Python. Then you just have to manage your paths consistently. The easier way to do that is to use Anaconda distribution with environments.

from smt.

I realize that what I suggest depends on the hardware architecture as well and will only work with a windows amd_64 (which is the architecture of my machine with which I generate SMT binaries).
Otherwise you have to compile SMT successfully. Again for that, I would suggest to install Anaconda distribution.

from smt.

I have installed Anaconda with python 3.73 (have another environment for 2.7) , installed SMT using 'pip install smt' . Whn I run some of the cases in the tutorial (LS, QP, Krigging) it runs fine , but stops when I run the RMTB case. I am attaching the sc

ree shot , as you can see .pyc files are there , but the error I get is 'smt.examples' module not found.

from smt.

Examples are not meant to be installed (the smt.examples package is not found hence the error). It works when installing in development mode pip install -e smt_folder because the code is in the smt_folder.

If you want to make it work, copy rans_crm_wing.py and run_rans_crm_wing_rmtb.py in a directory, go in that directory, replace from smt.examples.rans_crm_wing.rans_crm_wing ... by from rans_crm_wing ... then just execute python run_rans_crm_wing_rmtb.py

from smt.

That is it ! working now. I guess I need to do the same for all the other cases in 'examples' directory. Btw, there are plot commands in the file but I did not see any plots, shoild I remove the 'agg' option in the Mathplotlib?

from smt.

Indeed, comment out the matplotlib.use("Agg") line and you should see the plots.
