ipopt

问题 I'm completely new to Python and most aspects of compiling C. My default python interpreter is the anaconda interpreter for python 2.7. I'm trying to install pyipopt following these instructions: https://github.com/xuy/pyipopt. Pyipopt installed to /usr/local/lib/python2.7/dist-packages/pyipopt , but when I try import pyipopt I get an error saying that pyipopt wasn't found. I then tried copying the installed folder into Anaconda's pkgs folder. At first it said Error: import pyipopt

问题 I'm trying to create an AWS Lambda Deployment Package, so I can use it as an AWS Lambda Layer. Specifically, I'm trying to use the ipopt sovler, in conjuction with the pyomo and cython. I can get the pyomo packaged without issue, but when I try to pip install ipopt for the package I get an error: ERROR: Command errored out with exit status 1: command: 'c:\python36\python.exe' -u -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'C:\\Users\\username\\AppData\\Local\\Temp\\pip-install-rir

问题 I am using Gekko for selecting A-optimal experiments for a set of reaction kinetics. The objective function is to minimize the trace(inv(Z'Z)) where Z is a scale sensitivity matrix computed by linearizing the ODEs around its parameters. As you can see the objective function involve the inverse of Z'Z. I used the numpy (and even scipy) inverse function and I run to the following error: "No loop matching the specified signature and casting was found for ufunc inv" I really don't know what's
