GitHub user justincui closed a discussion: the pyfury demo code shown in the
website doesn't work with pyfury :(
The following demo code shown in the Fury website cannot be run with
pyfury==0.4.1 (the latest):
```
from typing import Dict
import pyfury
class SomeClass:
f1: "SomeClass"
f2: Dict[str, str]
f3: Dict[str, str]
fury = pyfury.Fury(ref_tracking=True)
fury.register_class(SomeClass)
obj = SomeClass()
obj.f2 = {"k1": "v1", "k2": "v2"}
obj.f1, obj.f3 = obj, obj.f2
data = fury.serialize(obj)
# bytes can be data serialized by other languages.
print(fury.deserialize(data))
```
Environment:
`RHEL9.2 (5.14.0-284.25.1.el9_2.x86_64 #1 SMP PREEMPT_DYNAMIC )`
`python 3.9.16`
Steps to reproduce:
```
1. python3 -m venv .venv
2. source .venv/bin/activate
3. pip install --upgrade pip
4. pip install pyfury
5. python a.py # the demo code
```
It prints the following error:
```
/data/try_fury/.venv/lib64/python3.9/site-packages/pyfury/__init__.py:67:
RuntimeWarning: Fury format initialization failed, please ensure pyarrow is
installed with version which fury is compiled with: No module named 'pyarrow'
from pyfury.format import * # noqa: F401,F403 # pylint: disable=unused-import
Segmentation fault (core dumped)
```
According to the error message, I install the pyarrow. I try the following
`pip intall pyarrow`
`pip install pyarrow==14.0.0 # according to README in fury.python`
`pip install pyarrow==12.0.0 # according to setup.py in fury/python`
None works.
In the error message, it complains the numpy 2.0.0 is incompatible. I install
numpy with `pip install numpy==1.26.4`
```
>>> pip list
