add raster layer failed in Example02_raster_Data

[shenweiqing]

Hi，I have a problem about adding and showing a raster on the map. I would appreciate any help in debugging and tracking down the error source.
I pull the lastest geonotebook image by run the code
pull geonotebook/geonotebook and use default config
When I run M.add_layer(rd, opacity=1.0, gamma=2.5) in 02_Raster_Data.ipynb,
nothing appears on the map. (I have tried chrome、Firefox and edge web browser)
But I think I read the raster image, because I can see the max and min values of the bands, besides M.layers is not an empty collection.
when I press F12 to see the chrome web browser console message. There is a log reads

I enter the container and try to check if there is a file names 7.png, but i find none.
docker exec -it containerid /bin/bash
find / -name 7.png
Please let me know what additional info would be helpful in debugging this.
Thanks!
