无法在 Arcgis notebook (GIS) 中运行 python 包

如何解决无法在 Arcgis notebook (GIS) 中运行 python 包

我正在尝试在 Arcgis 笔记本中运行 python 可视化包 (altair)，但出现此错误：

RuntimeError                              Traceback (most recent call last)
In  [1]:
Line 17:    color='z:Q'

RuntimeError: make_tuple(): unable to convert arguments to Python object (compile in debug mode for details)

这是我的代码：

import altair as alt
import numpy as np
import pandas as pd

# Compute x^2 + y^2 across a 2D grid
x,y = np.meshgrid(range(-5,5),range(-5,5))
z = x ** 2 + y ** 2

# Convert this grid to columnar data expected by altair
source = pd.DataFrame({'x': x.ravel(),'y': y.ravel(),'z': z.ravel()})

alt.Chart(source).mark_rect().encode(
    x='x:O',y='y:O',color='z:Q'
)
