file not found error

I am able to install greppo package. But getting this error:

Can you check if you have specified the path of the file properly? It is best to pass the absolute path of the file.

[shantanuo]

Tried. Same error. Is there a docker image for this?

[krish-adi]

Here is a Dockerfile: https://github.com/greppo-io/greppo-demo/blob/main/Dockerfile

[shantanuo]

Even docker did not work:

#0 6.641       Failed to get options via gdal-config: [Errno 2] No such file or                                                                              directory: 'gdal-config'
#0 6.641       A GDAL API version must be specified.

I am using ARM processor. May be that is not compatible with this.

[krish-adi]

The Dockerfile was tested both on a M1 and on an Intel chip. Do you have your code somewhere, that I could debug?

[shantanuo]

I was not using the app.py file from tests folder. I used
cd library/tests

then used this command:
greppo serve app.py --host 172.31.38.540

and got this error:

fiona.errors.DriverError: tests/data/us-states.geojson: No such file or directory

When I tried this command it worked as expected:
greppo serve v30.py --host 172.31.38.540

I appreciate your help.

[shantanuo]

When I moved the app.py file to /greppo/library/ folder it worked as expected. I think it should be made clear in the documentation.
But the problem is that I get "KeyError: EE_EMAIL". I am a member of google earth service. But I do not know my EE_EMAIL

[shantanuo]

I managed to solve the credentials problem. But when I used this code...
https://docs.greppo.io/mental-model.html

got this error:

TypeError: overlay_layer() takes 1 positional argument but 2 were given

[krish-adi]

Could you provide me a snippet of the code where you use overlay_layer ?

[shantanuo]

I used all the code mentioned on this page...

https://docs.greppo.io/mental-model.html

This code line did not work:

app.overlay_layer(
    data_gdf_1,
    name="Communes",
    description="Communes in Normandy, France",
    style={"fillColor": "#F87979"},
    visible=True,
)

In fact all the samples in quickstart guide having overlay_layer() method has this problem. May be I have not installed the module correctly.

By the way greppo seems to be awesome. I have seen other high level modules, but it looks like highest level module!

[krish-adi]

I'll take a look into this. In the meanwhile, can you use the vector_layer instead?

import geopandas as gpd
from greppo import app

data_gdf = gpd.read_file("./data/communes.geojson")

app.vector_layer(
    data = data_gdf,
    name = "Communes",
    description = "Communes in Normandy, France",
    style = {"fillColor": "#F87979"},
)

They are both the same. But overlay_layer use vector layer internally.

I had the same problem yesterday. I just try the vector layer module and as well the overlay layer and all are working perfectly !

.. and for the record, Greppo is amazing ! Amazing work Adithya Krishnan 😎

[shantanuo]

Yes "vector_layer" works as expected. A novice (like me) may think that those 2 are different. Please update the documentation if required.

[srizer]

For what it's worth, I also had this issue and it seems to have been resolved by explicitly setting data=data_gdf as opposed to just having data_gdf.

[shantanuo]

Yes. Setting data=data_gdf explicitly solved the problem. Thanks @srizer
Can someone fix the documentation and examples?

[krish-adi]

You could make a PR to the docs repo: https://github.com/greppo-io/greppo-docs
