How do I get around the traceback error: module 'QuantLib' has no attribute 'BaroneAdesiWhaleyEngine'?
Do I need to manually install QuantLib and specifically this Engine? How do I do that?
Thank you for any help.
Since version 1.20 (release notes) the class was exported to Python as BaroneAdesiWhaleyApproximationEngine, which was its name in C++ all along. The old name was kept available for a while, but in version 1.24 (release notes) it was removed. You'll have to use the new name now.

I have been trying to understand how Tensorflow works by executing some of the codes present as samples in the online tutorials. However, when I execute the code, I run into either of the 2 problems below:-
1. module 'tensorflow' has no attribute 'placeholder'
2. module 'tensorflow_core.compat.v1' has no attribute 'unpack'
I had tensorflow version 1.14 installed earlier in Anaconda. I was not able to upgrade to tensorflow 2.0. So I unistalled Anaconda and did a reinstallation along with the newer version of tensorflow. I did this primalrily because several of the function definitions had changed. Order of inputs and attribute names like unpack for example. But with the newer version even placeholder is not being recognised. I checked online and used tf.disable_v2_behavior() to use the previous version even though I have the latest version installed. But then I get the naming error again. I am really confused how to proceed. I have been at it since hours. Any suggestions ?
I have an OR problem and using an academic version of cplex library in the jupyter notebook by python 3.6.
When I am calling the following command I get an error:
command:
solution=mdl.solve(log_output=True)
error:
TypeError: can't pickle dict_keys objects
when I removed (log_output=True) everything works just fine, but I need the detailed output.
Since this is a crossed reference question, I would rather not repeat myself and confuse other people. The reason to ask here is that different scholars are attending these two reference webpages.

If I find my answer in stackoverflow I will share the solution procedure here and on github.
From the solution found in the external link: the problem is fixed in docplex ersion 2.10.150. Upgrading to that version fixes the problem.
As Daniel Junglas mentioned there were some inconsistencies between the two version of docplex toolbox and cplex 12.9 academic version I was using. A member of IBM team noticed the problem and updated the docplex version. And the lastest version up to date 07/08/2019 is here https://pypi.org/project/docplex/2.10.150/.
Many thanks to IBM Team.
I am running Julia v1.1.1 on a windows 10 machine.
I recently went back to update my Julia v0.6.2 code to Julia v.1.1.1 as my code is no longer supported in Julia v0.6.2 anymore.
I was wondering if anyone knows how to name an Ngramdocument after a string, I think the function used to do this was in the TextAnalysis package :
name!(Ngramdocument, string)
However, recently now that I am trying to update my code to Julia v1.1.1 it is saying that the function is undefined. I was wondering if maybe I was wrong in assuming that the function was defined in the TextAnalysis.jl package or if they changed the name. I have not been able to find documentation of a name change however.
name! was changed to title!. title!(Ngramdocument, string) should work as expected in Julia 1.1.1 with the recent TextAnalysis.jl release. You can see the relevant pull request here.
While migrating code, if you face such undefined function errors, you may quickly find the changes looking at the commit history of the package repository or using search function on the GitHub repo of the package.
I am using version 1.9.0 of the RED HAWK IDE on RedHat 6.3.
After install RedHawk I looked at the video http://www.youtube.com/watch?v=wN9p8EjiQs4.
I tried to run through the example but I notice I am missing a large amount of the components she has like add_const_ff, complex_to, noise_source, vector_sink, medianfilter.
Should I have them? Is there a package I am missing?
Adding stuff to get the checker to except my question. I tried, then tried. Going to try.
Here you can find several packages from RedHawk developer:
https://github.com/Axios-Engineering
https://github.com/RedhawkSDR
You can try to download and build them
All of the components you mentioned except for the medianfilter are part of the GNUHawk library of components and can be found at https://github.com/RedhawkSDR/integration-gnuhawk/tree/master/components.
The median filter is part of the basic-components library and can be found at https://github.com/RedhawkSDR/basic-components
I tried to build the example package from here but sadly I get following error:
error: Couldn't find package std in any of the workspaces in the RUST_PATH (C:\U
sers\User\Desktop\test\hello.rust:C:\Users\User\Desktop\test\hello:C:\Users\Use
r.rust)
Now it's kinda obvious that there is some issue with RUST_PATH but I am somewhat unable to find documentation concerning it.
note: I'm using Windows 8 64 bit and Rust 0.8
Rustpkg has been removed from basic library and moved into librustpkg.
There are alternatives like Makefile or CMake, but I assume the preferred version it's using cargo-lite.
My advice is just look at Rust-CI for a project that uses package manager you like most and copy it's build shamelessly.
UPDATE: A new package manager for rust has been announced. It's called Cargo. We'll see how it works out, but that is possible future default.
Rustpkg has been removed from Rust. Hopefully we will get something to replace it.
