Problem to run the RasterioSource on Google Colab

[marcosdavi1415]

Hi! I am facing a problem to run the first cell about RasterSource. This mensage is shown: "Unable to open EPSG support file gcs.csv. Try setting the GDAL_DATA environment variable to point to the directory containing EPSG csv files". Could someone tell me how i can solve this problem?

Note: Edited the answer. Hadn't seen this was about Colab before.

This is how you're supposed to do it in Colab. Let me know if this works.

import os
from subprocess import check_output

os.environ['GDAL_DATA'] = check_output('pip show rasterio | grep Location | awk \'{print $NF"/rasterio/gdal_data/"}\'', shell=True).decode().strip()

Thanks again. I did the suggested, but the problem continues. Can you run the colab cells?

Here is a working example: https://colab.research.google.com/drive/1qUl_6McbLJr9KjrhHnx_SWbSYkLPL2uW?usp=sharing

It turns out I needed to set an AWS-related env var as well. LMK if that works.

The previous issue was resolved, but only when I run on the master branch. When I compile on the corresponding branch of the colab, which is the cd-blog, the previous problem remains. And some dependencies that are present only in the cd-blog branch are needed to run the other cells of the colab, . Would it be possible to solve the previous problem to use the respective cd-blog branch?

I did not realize you were running the Change Detection notebook.

For the RV branch used in that notebook, it seems like a kernel restart is required after setting the environment variables. I have updated the notebook to move the env var step above the reboot step: https://colab.research.google.com/drive/1Ex5xbAx4epzReCQDsqvZLoTpF6AtfnHr?usp=sharing

Thanks a lot for the help. Now the problem is solved and I can run all the code.
