如何在pyqt5中使用geemap而不是folium？

Question

在以下代码中：

import sys
import io
import folium
from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout
from PyQt5.QtWebEngineWidgets import QWebEngineView
import geemap

class my_app(QWidget):
    def __init__(self):
        super(my_app, self).__init__()
        self.setWindowTitle('GRSGA')
        layout = QVBoxLayout()
        self.setLayout(layout)
        cordinate = (32.3265, 52.65241)
        map = folium.Map(title='geors', zoom_start=8, location=cordinate)
        data = io.BytesIO()
        map.save(data, close_file=False)
        web_view = QWebEngineView()
        web_view.setHtml(data.getvalue().decode())
        layout.addWidget(web_view)
if __name__ == "__main__":
    app = QApplication(sys.argv)
    app.setStyleSheet('''
        QWidget{
        font-size: 35px
        }
    ''')
    myapp = my_app()
    myapp.show()

    try:
        sys.exit(app.exec_())
    except SystemExit:
        print('closing window')

我可以在pyqt中显示folium地图。但是我想使用geemap而不是folium，就像下面的代码一样：

cordinate = (32.3265, 52.65241)
    map = geemap.Map(title='geors', zoom_start=8, location=cordinate)
    data = io.BytesIO()
    map.save(data, close_file=False)
    web_view = QWebEngineView()
    web_view.setHtml(data.getvalue().decode())
    layout.addWidget(web_view)

此代码返回以下错误：

 Traceback (most recent call last):
  File "D:\earth engine\gee_app\train1.py", line 28, in <module>
    myapp = my_app()
  File "D:\earth engine\gee_app\train1.py", line 17, in __init__
    map.save(data, close_file=False)
  File "D:\earth engine\gee_app\venv\lib\site-packages\ipyleaflet\leaflet.py", line 2220, in save
    embed_minimal_html(outfile, views=[self], **kwargs)
  File "D:\earth engine\gee_app\venv\lib\site-packages\ipywidgets\embed.py", line 302, in embed_minimal_html
    snippet = embed_snippet(views, **kwargs)
TypeError: embed_snippet() got an unexpected keyword argument 'close_file'

我该怎么解决它呢？

geemap.Map()的save()方法不接受close_file，而且fp必须允许写入字符串而不是字节，因此必须使用io.StringIO()。

class my_app(QWidget):
    def __init__(self):
        super(my_app, self).__init__()
        self.setWindowTitle("GRSGA")
        layout = QVBoxLayout(self)
        web_view = QWebEngineView()
        layout.addWidget(web_view)

        cordinate = (32.3265, 52.65241)
        map = geemap.Map(title="geors", zoom_start=8, location=cordinate)

        data = io.StringIO()
        map.save(data)
        web_view.setHtml(data.getvalue())
