Errors in running notebook number 2

[BobbieZHU]

Hi!

When I am running the cell:

for file in tqdm(files):
df = read_data_frame(file)

signals = []
for row in df.itertuples(index=False):
    signals.append(row)
    
db.insert_signals(signals)

There is always a error named: OperationalError: no such table: signal. I uploaded the detail explanation on the attachment.

I have difficulty in solving this problem. Could you please give me some advice?

Thanks，
Bobbie

By the way, I am using the Jupyter embedded in Anaconda.

You are right. I am missing an update to the code that I will do very soon. I will let you know when it is ready. Thank you for letting me know!
