ImportError Pyo

Question

I'm trying to import pyo in python3.8.8 and I'm not getting any results. When I try to run the command: Traceback (most recent call last): File "<pyshell#0>", line 1, in import pyo File "C:\Users\andre\AppData\Roaming\Python\Python38\site-packages\pyo_init_.py", line 28, in from .lib import analysis as analysis File "C:\Users\andre\AppData\Roaming\Python\Python38\site-packages\pyo\lib\analysis.py", line 32, in from ._core import * File "C:\Users\andre\AppData\Roaming\Python\Python38\site-packages\pyo\lib_core.py", line 58, in from .._pyo import * ImportError: DLL load failed while importing _pyo: Impossibile trovare il modulo specificato.

How can I solve this?

Answer 1

I assume you are on windows. What version of pyo do you have installed? I saw that it was only version 1.0.1 that python 3.8 support was introduced. Try uninstalling pyo, then make sure you install the newest version. Also, did you install with pip? If you did, try installing from their downloadable releases on github. What code did you write that caused this error? I need to see your code.

Answer 2

Looks like you're using pc032 (032bit) Python. Last PyO version with pc032 (on Win) support is [PyPI]: pyo 1.0.1 (from 191127). But I didn't see the Python 3.8 .whl among files (neither for a couple of older versions).

Just out of curiosity: how did you install PyO?

In order to get things going either:

• Switch to pc064 (064bit) Python

• Use a (pc032) Python version that prebuilt .whl exists for

• I've built v1.0.4 (latest at answer time) and placed the .whls at [GitHub]: CristiFati/Prebuilt-Binaries - (master) Prebuilt-Binaries/PyO/v1.0.4. Download and install the preferred one (check [SO]: Installing pygraphviz on Windows 10 64-bit, Python 3.6 (@CristiFati's answer) (at the end) for more details about the process)
