I'm trying to reproduce the code from this link on Google Colaboratory but my Colab Notebook crashes for reasons I don't understand. Is it possible to get this to work properly?
I can confirm the crash in this notebook.

This issue has to do with the fact that Cartopy and Shapely aren't friends...
Shapely is preinstalled in Google Colab, causing a plain install of Cartopy to give problems.
You will have to uninstall Shapely first and reinstall it with no-binary.
Also in order for Geoviews to show plots in Google Colab you will have to call gv.extension('bokeh') in every cell where you want to plot something.
Follow this notebook to see the example code of Geoviews working correctly in Google Colab:

I'm trying to do some object tracking on a video using Google Colab but I'm facing the issue below. Tracking is only done in the first frame of the video and not in the rest. I'm working with exactly same files and same commands both on my computer and Google Colab.

It seems like TensorFlow's version caused this problem. Here is my solution:
!pip install tensorflow==2.3.0
I have been using ipywidgets in google colab for a while but it today it started asking me to enable third party widgets and presented codes for custome widget managers. The widgets arent getting displayed any more. Was it because of an google colab update or am I making an error. I have attached a picture.
This issue has been detected by google colab team, downgrading ipywidgets to 7.1.1 is the easiest way to solve the problem now.
What i have done is downloaded a already preset skeleton for my dash app using a !wget function in Jupyter Notebook, I was wondering how could i launch the app?
Is there something similar to this line of code i could use python3 spacex_dash_app.py?
Thank you.
The ! symbol passes your commands to the underlying shell running Jupyter.
Similar to prefixing wget with !, you can run !python3 spacex_dash_app.py, after making sure that spacex_dash_app.py is in the same working directory as your Jupyter notebook.
Going through a finance tutorial. The tutorial uses import pandas_datareader to read in stock data from Yahoo.
Running this on my local computer works. But it does not work through Google Colab. Is this a limitation of Jupyter notebooks?
I'm trying to use google map API to visualize some data in jupyter notebook. Here is the code I used to display basic map in jupyter:
import gmaps
import os
import json
import gmaps.datasets
gmaps.configure(api_key="AIz....")
fig=gmaps.figure()
fig
After I ran the code, nothing was displayed. I used my own google API key and couldn't figure out why the map isn't displayed. I'm new to the geojson field, so any idea or thoughts is appreciated.
Did you make sure Widgets are enabled in your jupyter? try this before you run Jupyter:
jupyter nbextension enable --py gmaps
jupyter nbextension enable --py widgetsnbextension
If you are using JupyterLab you can check out the steps in the documentation here
