There is a bug in the VS 10 IDE that renders property dialog fields blank

CMake must use a full path for this file which then triggers the VS 10

Please help me, I have been looking for a way to solve this problem for 2 days, but without success, I am desperate

Go to here and download llvmlite package for your python version, e.g. llvmlite‑0.35.0‑cp39‑cp39‑win_amd64.whl for Python 3.9.
Then install pip install llvmlite‑0.35.0‑cp39‑cp39‑win_amd64.whl.
Probably llvmlite is not yet officially supported on Python 3.9. That's why there are only unofficial builds like on this site.
Also if you need numba then go to here and download/install numba‑0.51.2‑cp39‑cp39‑win_amd64.whl. Latest numba 0.52.0 is not yet compiled by this site owner for Python 3.9, only version 0.51.2.
Also when installing numba you may need to pass key --no-deps to pip to ignore installing dependencies, like pip install --no-deps numba‑0.51.2‑cp39‑cp39‑win_amd64.whl because numba 0.51.2 wants a bit older version of llvmlite by default. Also few small extra dependencies are needed to be installed manually. So all steps for installing on Win Python 3.9 64-bit are:
pip install llvmlite‑0.35.0‑cp39‑cp39‑win_amd64.whl (.whl file from here).
pip install --no-deps numba‑0.51.2‑cp39‑cp39‑win_amd64.whl (.whl file from here).
pip install numpy importlib-metadata (small few extra dependencies via regular pip install without downloading).
PS. Site by link mentioned above has only Windows packages. Also this site has many other popular wheels packages for Python, most of them are placed on this site because they are not currently available inside official PIP repository..

Install llvm {version} greater than 7 using command
suda apt install llvm-{version}
Than to install numba or llvmlite {package} use command
LLVM_CONFIG={path to llvm-config file} pip install {package}
For example (For llvm version=8)
LLVM_CONFIG=/usr/bin/llvm-config-8 pip install numba==0.48

llvmlite does not have support for python 3.9 yet. Uninstall python 3.9 and download python 3.8.7 and try again. This solved for the problem for me.

Another approach is to install llvmlite version which is directly compatible with Python 3.9.
today I successfully did that with pip install llvmlite==0.36.0rc1; you may want to use some other latest version.

Trouble with control module .statespace .pzmap

I calculate the zeros and poles of a system with control.StateSpace. In the following I want to use control.pzmap to display the result but the last doesn´t work. I can print sys and it seems okay but not as parameter of control.pzmap.
Can someone pls help me?

D= [[0],[0],[1]]
print(A)
print(B)
print(C)
print(D)
fig=plt.figure(1, figsize=(10,6)); fig.clf()
plt.show()
sys=control.StateSpace(A,B,C,D) #calculation of poles and zeros of the given system
print(sys)
a=sys.pole()
print(a)
control.pzmap(sys) #should make a diagram of poles and zeros, but doesn't work

You should consider upgrading via the 'c:\anaconda3\python.exe -m pip install --upgrade pip' command.

Ok, I've installed anaconda environment (just for you ;) ) to pinpoint the problem. It seems thats not just your machine and using the package that you use is a little difficult then trivial.
It seems that you have two problems.
First problem is, one of the packages you use depends on slycot. But slycot requires some compiling work on the background in order to install itself. Compiling the files on your pc requires having a compiler installed on your computer. Preferred compiler for this package is Visual Studio 2017. If you check the error message carefully, it is asking you to download and install it from this page.
Second problem is something I am not familiar with. It is complaining that the input space has to be the same size with the output space.
NotImplementedError: StateSpace.zero only supports systems with the same number of inputs as outputs.
But then again, this might be caused by the first problem.
So, let's install the VS 2017 first and see if that resolves it. If not, we'll see if anything has changed and proceed from there.

Getting dependencies error while installing ViZDoom

I am trying to install ViZDoom on Ubuntu system. I am following the steps given the following link https://github.com/mwydmuch/ViZDoom/blob/master/doc/Building.md.
However, I am getting the following error:

Does Poetry install --no-dev need Rust to be installed?

I'm installing Poetry in a container in my Raspberry pi 3b+ (Lite buster February 2020). I use the image arm32v7/python:3.7-slim-buster.
Here is the Dockerfile:
FROM arm32v7/python:3.7-slim-buster
RUN apt-get update
RUN apt-get install libssl-dev -y
RUN apt-get install libffi-dev
RUN apt-get install build-essential -y
RUN pip install poetry
RUN pip install --upgrade pip
COPY ./pyproject.toml /app/
WORKDIR /app/
RUN poetry install --no-dev
COPY ./rpiserver /app/rpiserver
RUN poetry install --no-dev
ENTRYPOINT poetry
When docker runs the step with poetry install --no-dev it installs many packages including orjson (2.6.3) which requires "Rust nightly toolchain". So it fails!
Here is the error message:

I didn't find any Poetry documentation that was saying to install Rust (because orjson needs maturin, which needs cargo, which needs Rust? Right?).
In order to solve this issue, I decided to install cargo and maturin in my image by editing the Dockerfile.
However I got a new issue.

Why do I need Rust in this situation?

Poetry doesn't depend on Rust.
But you are depending on orjson, which is implemented, at least partly, in Rust. As a result, installing it from source¹ requires a Rust toolchain and the maturin build tool.
Add pip install maturin back to your Dockerfile as it was before or, better yet, add it to your project's dependencies.
You will also need to install cargo. A multi-stage build might be the best solution, but the simplest is probably to install packages into the existing image, e.g. via something like
RUN apt-get install cargo
in your Dockerfile.
¹Binary wheels might be available for some platforms, in which case the Rust tooling presumably wouldn't be required, but since pip is trying to build from source I suspect no compatible wheels are available for ARM.
