ValueError：无法识别的引擎 zarr 必须是以下之一：['scipy', 'store']

问题描述

我正在尝试打开 zarr 文件，

import pandas as pd
import xarray as xr
xf = xr.open_zarr("../../data/processed/geolink_norge_dataset/geolink_norge_well_logs.zarr")

但是出现了错误：

---

    480         engine = plugins.guess_engine(filename_or_obj)
    481

    483 
    484     decoders = _resolve_decoders_kwargs(

    135                 f"unrecognized engine {engine} must be one of: {list(engines)}"
    136             )

ValueError: unrecognized engine zarr must be one of: ['scipy','store']

谁能帮忙解决这个问题？ 我可以确认我已经安装了 scipy 和 store 包。

解决方法

您可能还需要安装 zarr 包：

pip install zarr

如果这不起作用，请尝试：

pip install xarray[complete]
