The map cannot be loaded using the Python API

[shicuiduo]

Hello, after I set up all the configuration the way you did, running the Python API script failed to load the map. The percentage of maps loaded is always 0%. Do you know what caused it? Looking forward to your reply. Thank you very much.

Hi, thanks for posting an issue.

Did you follow the README instructions to download the assets and place them in the appropriate folders? This looks like the server isn't able to let the client download the asset.

[shicuiduo]

Yes. I put the geojson.json file into the mongo/setup folder. Unzip hdmaps, plugins, preview, and vehicles into the server/assets folder. Download the individual map files from the maps folder in google-drive separately (not all of them, only 30) and place them into the server/assets/maps folder.Is that right?

Hey, I've fixed the above problem (The reason is that the map is not downloaded to the maps folder.).
But the WideFlatMap Map cannot be loaded (WideFlatMap has been downloaded to the maps folder), other maps can be loaded.

Hi, I haven’t used WideFlatMap before. Is there any error messages?

[shicuiduo]

There is no error message. When running the python API, the program does not print anything, and svl keeps displaying the following:

It works fine for other maps but for the specific map you mentioned the client is stuck at “APIReady”, is this correct?

[shicuiduo]

Yes. Can you load the "WideFlatMap" map using the python api?

[YuqiHuai]

Sorry for the late response. I’m gonna work on trying to resolve this issue today.

Thank you for your reply. Recently I discovered something new: by modifying the SORA-SVL-master\mongo\setup\vehicles. json file, you can change the sensors configuration parameters of the vehicles. This is exciting news.

@shicuiduo After some investigation, the problem was caused by Google Drive adding ".zip" at the end of each asset file for maps.

You can run following Python code

import os
import shutil

for x in os.listdir('.'):
    if x.endswith('.zip'):
        shutil.move(
            os.path.join('.', x),
            os.path.join('.', x[:-4])
        )

at the maps dir and remove all the ".zip".

You could have loaded some other maps because those were cached, not downloaded from the local cloud. The server was basically looking for a file named "assetGuid" but under the maps directory you had "assetGuid.zip"

Hello,I have the same problem about load all maps.
I used the toolset/correct_maps_dir.py ,and put the geojson.json file into the mongo/setup folder.
When I run the example/01-load_map.py first time,the terminal show


and I run the example/01-load_map.py again,the terminal show


and it stuck

I have tried to make a new file to load map, but have the same response when sim.load is executed.
Could somebody know what should I do?

@binzhao1 Hi, sorry due to google drive no longer being free for my academic group account, I’m exploring alternative options to host the files. For now it is still available at #80
