我正在尝试使用 pyO3 使用 Rust 中的 numpy,所有这些都在 conda 环境中。为了让 pyO3 链接,我也使用 conda 安装了 GCC 工具链。

我现在可以做一些简单的事情,比如显示sys.path。但是,当我尝试导入 numpy 时,如下所示:

use pyo3::prelude::*;
use pyo3::types::IntoPyDict;

fn main() -> PyResult<()> {
    let gil = Python::acquire_gil();
    let py = gil.python();

    let r = py.import("numpy");
    match r {
        Ok(_) => println!("OK"),
        Err(e) => e.print(py),
    }

    Ok(())
}

发生以下情况:

Traceback (most recent call last):
  File "<HOME>/anaconda3/envs/pyrust/lib/python3.7/site-packages/numpy/__init__.py", line 140, in <module>
    from . import _distributor_init
  File "<HOME>/anaconda3/envs/pyrust/lib/python3.7/site-packages/numpy/_distributor_init.py", line 33, in <module>
    with RTLD_for_MKL():
  File "<HOME>/anaconda3/envs/pyrust/lib/python3.7/site-packages/numpy/_distributor_init.py", line 18, in __enter__
    import ctypes
  File "<HOME>/anaconda3/envs/pyrust/lib/python3.7/ctypes/__init__.py", line 7, in <module>
    from _ctypes import Union, Structure, Array
ImportError: <HOME>/anaconda3/envs/pyrust/lib/python3.7/lib-dynload/_ctypes.cpython-37m-x86_64-linux-gnu.so: undefined symbol: PyUnicode_FromFormat

有趣的是,当我只键入 时python -c "import numpy",并没有出现问题。

如果有帮助,我会使用它RUSTFLAGS="-C linker=$CC" cargo +nightly run来构建和运行代码。
