`BadZipFile` when trying to run Dash for the first time #28

Open JannisNe opened 3 months ago

JannisNe commented 3 months ago

I tried to start up dash for the first time and I got an error when it tried unzipping the models file with the traceback below. I also tried downloading it manually from https://github.com/daniel-muthukrishna/astrodash/blob/master/astrodash/models_v06.zip with the same result. Also, unzipping manually gives me an error. Is the file damaged? 

Downloading data files from https://github.com/daniel-muthukrishna/astrodash/blob/master/astrodash/models_v06.zip?raw=true... 
This download contains the Tensorflow models trained using deep learning. 
The file to be downloaded is ~200MB. However, this is a one time download, and will only occur
the very first time that this version of DASH is installed.

Hi! Jut would like to second this problem.

I have a M2 Macbook air, and I am using a python = 3.8 environment. I also get the same error when trying to run astrodash for the first time.

EDIT: I can't even unzip it manually, the file is 134bytes. I went to your proposed solution: https://zenodo.org/records/7760927 , downloaded the file and replaced in manually where astrodash is installed.
