Load the islands dataset and obtain the total number of observations.

Sure, I'd be happy to help. Here's how you can obtain the total number of observations in the "islands" dataset:
```python
import seaborn as sns
# Load the 'islands' dataset
df = sns.load_dataset('planets')
# Obtain the total number of observations
num_observations = df.shape[0]
print("Total number of observations in the 'islands' dataset:", num_observations)
```
This should output the total number of observations in the "islands" dataset. Let me know if you have any more questions!

rizomuv 软件提示 WARNING: "Packing overflow. Some islands or groups cannot fit in tile with the requested Texel Density and/or scaling constraints. Please lower the target texel density, or increase the texture map resolution, or add tiles or increase their dimensions, or release Min. Scaling constraints."
根据您提供的信息,这个警告是由 RizomUV 软件生成的。它表明在使用指定的 Texel Density(纹素密度)和缩放约束条件时,某些区域或组无法适应贴图。建议您尝试以下解决方案之一:
1. 降低目标纹素密度:减少所需纹素密度,这样可以让更多的岛屿或组适应贴图。
2. 增加贴图分辨率:通过增加贴图的分辨率,可以提供更多的空间以适应所有的岛屿或组。
3. 添加或增加瓷砖尺寸:可以尝试添加更多的瓷砖或增加现有瓷砖的尺寸,以便更好地容纳岛屿或组。
4. 释放最小缩放约束:如果应用了最小缩放约束,您可以尝试解除这些约束,以便更灵活地布置岛屿或组。
请根据您的具体情况尝试上述解决方案,并根据需要进行调整。
islands岛屿
以下是使用 Python 语言实现的代码:
```python
n = int(input())
heights = sorted([int(input()) for i in range(n)])
water_level = 0
island_count = 0
for h in heights:
if h <= water_level:
continue
else:
island_count += 1
water_level = h
print(island_count)
```
这段代码首先读入高度值,然后按从低到高的顺序进行排序。接着,使用 for 循环遍历每个高度值,并根据上述思路进行判断和计算。最后输出岛屿数目即可。
希望能够帮助到你!
