ValueError: could not convert string to float: 'BTCUSD'

[GrahamboJangles]

Using Google Colab. python graphwerk.py returns:

60
Traceback (most recent call last):
  File "/content/inpredo/src/graphwerk.py", line 90, in <module>
    graphwerk(iter, iter+12)
  File "/content/inpredo/src/graphwerk.py", line 31, in graphwerk
    open.append(float(pd[start][1]))
ValueError: could not convert string to float: 'BTCUSD'

I edited the ad variable in graphwerk.py to equal

ad = genfromtxt('/content/inpredo/financial_data/btcusd-1h.csv', delimiter=',' ,dtype=str)

Edit: After deleting the second column in btcusd-1h.csv with the string BTCUSD and editing graphwerk.py to specify my buy and sell folders, I now get this error:

60

Edit: Oh, I see. I overlooked the comment on line 29 in graphwerk.py.
