Re: [sympy] Parsing expressions problem | "ImportError: Clang is not installed, cannot parse C code"
Okay, I found "python-clang" on conda-forge and installed it.
$ conda list python-clang
# NameVersion Build Channel
python-clang 13.0.1 default_hccd1708_0conda-forge
I now receive the error message:
NotImplementedError: Only bool, int and float are supported
My understanding of this error message is that arrays such as
std::array are not currently supported.
Is this correct?

Re: [sympy] Parsing expressions problem | "ImportError: Clang is not installed, cannot parse C code"
It should be python-clang.

Re: [sympy] Parsing expressions problem | "ImportError: Clang is not installed, cannot parse C code"
Thanks for your prompt reply.
What is "clang-python" and from where may I download it?
A search on "clang-python" did return anything obvious.
I suggest that the documentation be updated with this required information.

Re: [sympy] Parsing expressions problem | "ImportError: Clang is not installed, cannot parse C code"
The error message should be improved there. You need clang-python.

[sympy] Parsing expressions problem | "ImportError: Clang is not installed, cannot parse C code"
Hello,
I am attempting to parse C code into Python using SymPyExpression but am
receiving the error message "ImportError: Clang is not installed, cannot
parse C code"
However, I'm quite certain that I have Clang installed
$ conda list clang

Puzzled.
Another unrelated issue. Just now, when I attempt to go
to https://docs.sympy.org/
I receive the message
404
There isn't a GitHub Pages site here.
