The latest version of symjit (v2.3.0) is now available (with thanks to
Jason). You can install it as `conda install -c conda-forge symjit`.
In addition to being more stable, Symjit should be significantly faster,
especially for certain workloads relevant to SymPy. The main improvements
are:

Thanks Shahriar.
Hi Isuru,
The Rust backend has a C API for communication with Python. However, it
expects the whole model as a JSON string, which may not be the most
convenient form for SymEngine. I think we need to design a better API that
is useful to SymEngine.
Thanks,

Hi Oscar,
I wrote a light wrapper around the symjit python backend. It can be
installed using `pip install funcbuilder`. The only dependency is numpy.
The GitHub repo is https://github.com/siravan/funcbuilder.
It can compile your example:
In [1]: from funcbuilder import FuncBuilder
In [2]: B, [x

It is and in some ways it is not realistic but actually in some ways
it is. A common case will certainly be small expressions e.g. for
simple ODEs as you show in the README. Another case thoug
Hi Oscar,
Yes, we can add symjit as another backend if it offers a C/C++ API.
We also have a pure C/C++ backend, just replace `LLVMDouble` by
`LambdaDouble`.

Hi Oscar,
Thank you very much for your response. I appreciate it. There is a lot to
think about.
Regarding the example, this is a tough test! It shows that there is a bug
in the x64-86 rust backend. Interestingly, the Python backend and the rust
one on ARM64 (MacOS) give the correct answer:

I'm sure it can be made faster. To be clear to anyone reading this

Hey Oscar,
SymEngine's lambdify can be used too. It uses numpy arrays to support

and other features of sympy.
from symengine import *
x = symbols('x')
e = x**2 + x
for _ in range(10):
e = e**2 + e
ed = e.diff(x)
f = lambdify([x], [ed])
print(f(.0001))

We have already debugged everything and merged the PR to conda forge:

You can install symjit with:
conda install -c conda-forge symjit
Enjoy!

Hi Jason,
Thanks for your help. I got conda-forge working. You can install symjit on
Windows and Linux (Mac will be coming soon).
Here is the meta.yaml that works:
```
{% set name = "symjit" %}
{% set version = "1.2.1" %}
package:
name: {{ name|lower }}
version: {{ version }}
source:

Hi,
The way conda forge works is that it starts from a source distribution and
compiles the code using their toolchain (they have a rust toolchain). This
generates conda binaries, not wheels.
So, to get it to build there on conda forge we have to debug any Rust
compilation or Rust->Setuptools/pyt
Hi,
I’m using setuptools. I should try conda next.
Currently, it comes with binaries for Windows, linux x86-64 (built on
ubuntu), and raspbian linux (aarch64). No Mac yet. I will try to compile it
on a Mac.
In the long run, it might be easier to rewrite it in pure python with
hardware dependenci
Dear Shahriar,
I opened a PR to package symjit for conda here:
https://github.com/conda-forge/staged-recipes/pull/29211
I've never tried building any rust packages. There are a couple issues, but
maybe it has to do with conda-forge. I'm not sure. If you have any tips you
can comment there.

Thanks a lot. Yes, I meant https://www.sympy.org/en/index.html. I will send

Regarding the name, I was thinking about a variation of lambdify but
couldn't come up with one, so I went with compile_func.

Yes, this looks interesting, especially that you choose a sane function
name "compile_func". We should have named lambdify that.

Hi Shahriar,
The symjit package sounds very interesting. I will have to take a look at it.
I'm not sure what the list of packages you are referring to is.
Presumably a PR to the website can add this?
