Google Datalab和Python问题

Question

I have a python script that runs perfectly in my IDE on my local machine, but when I run it on Google Datalab, it throws this error:

ValueError: could not convert string to float: '80,354'

The code is simple, and the graph prints in my Pycharm IDE, but not on GoogleDatalab.

plt.plot(new_df['Volume']) plt.show()

The error is related to the last line in the data. I'm using the date as an index. Here's what the data looks like? Is there a slash missing somehwere? What am I doing wrong or missing?

Answer 1

I was loading the data inappropriately. I was using pandas load_csv on my local machine, and BytesIO on in Datalab. The comma in the numberical value was throwing off the import of the data. I had to say that the delimiter is a "," and the thousand separator is also a ","
