Hello!

I am submitting my code for smoke testing and it is marked as “failed”. The log shows that my script exited without errors. I added a debug print to check the content of my final submission.csv file and it looks healthy:

At the end of `main.py`:

```python
with open('/code_execution/submission.csv' 'r') as file:`
    file_content = file.read()`
    print(file_content)`

```

This gave in the ouput:

```bash
uid,is_pathologic
v23gxj0m,0.6161804105900507
1r11q7uw,0.044185568153099174
cwbfuk9e,0.6816717708095468
t7zewviy,0.6011349427804435
w69hzgop,0.9367508045701831
(etc)

```

This confirms that:

1. the submission.csv was correctly created, at the location described in the [docs](https://www.drivendata.org/competitions/311/dat-parkinsons-challenge/page/989/)
2. the content is compatible with the expected format (header, coma-separated) etc

I fail to see why such predictions would not be compatible with a score evaluation.  
Or it is because smoke tests don’t get scored?

Thanks for your help

arovai

Hi @arovai , it looks like the ordering of your UIDs is incorrect - they should be in the exact same order as the submission\_format.csv in the smoke test execution environment, which you can read from `/code_execution/data/submission_format.csv`. Hope this helps!
