This is my first time using scrapy and I cant even install it, please help me!!

I'm a new Pyomo user, i try to convert an ampl model to pyomo and i found it's too hard to do this work.

When i create the var x with the set lev witch is indexed by a another set A, i get this error warning: Cannot apply a Set operator to an indexed Set component (lev).

Thanks in advance.

Ampl model and pyomo code is shown below

Ampl

I have this little project where I use pytest and pytest-dependency with tox to develop integration tests on some code. Until now I used one base class (BTestClass) with some common tests in the root directory and the specific tests for each code component in a test_Component.py file next to it implementing a TestC class that inherits from BTestClass.

Everything worked fine until then. Now I want to add a BTestClass2 for another set of components. So I added another layer of inheritance, but now it doesn't work, pytest validates the common A tests but then skips the tests that depend on it. I have no idea why.

Here's the filesystem layout:

I'm trying to write a Pyomo model where I have a set of variables, indexed by a j in {1,2,...,N} and, for every j, a i in {1,...,N_j}.

My code right now is:

Each time the function is called, 2 rows are written in the Excel file, but at the end of the application there is only the last 2 row in the file. Every time i call the Function the two new row overwritte the last two rows. I think it's because of this line:

I have a group with coupled disciplines which is nested in a model where all other components are uncoupled. I have assigned a nonlinear Newton and linear direct solvers to the coupled group.

When I try to run the model with default "RunOnce" solver everything is OK, but as soon as I try to run optimization I get following error raised from linear_block_gs.py:

File "...\openmdao\core\group.py", line 1790, in _apply_linear scope_out, scope_in)
File "...\openmdao\core\explicitcomponent.py", line 339, in _apply_linear self.compute_jacvec_product(*args)
File "...\Thermal_Cycle.py", line 51, in compute_jacvec_product d_inputs['T'] = slope * deff_dT / alp_sc File "...\openmdao\vectors\vector.py", line 363, in setitem raise KeyError(msg.format(name)) KeyError: 'Variable name "T" not found.'

Below is the N2 diagram of the model. Variable "T" which is mentioned in the error comes from implicit "temp" component and is fed back to "sc" component (file Thermal_Cycle.py in the error msg) as input.

N2 diagram

The error disappears when I assign DirectSolver on top of the whole model. My impression was that "RunOnce" would work as long as groups with implicit components have appropriate solvers applied to them as suggested here and is done in my case. Why does it not work when trying to compute total derivatives of the model, i.e. why compute_jacvec_product cannot find coupled variable "T"?

The reason I want to use "RunOnce" solver is that optimization with DirecSolver on top becomes very long as my variable vector "T" increases. I suspect it should be much faster with linear "RunOnce"?

Considering this project structure:

I'm trying to install Scrapy framework. After installing all dependent libraries and start installing setup.py file, I get this error message: "cl.exe' failed: No such file or directory" I'm working with python 3.6, Windows 7 64 bits. Here is the full error message:

Good day to you,
