Multiply two df in GPU (cudf)

Question

I have two dataframe in GPU. I want to multiply each element of each df. Here is a simple version of my dataframes:

import cudf
a = cudf.DataFrame()
a['c1'] = [1, 2]
b = cudf.DataFrame()
b['c1'] = [2, 5]

I want to see this output:

    c1
0   2
1   10

I am using a.multiply(b), however, I get error;AttributeError: DataFrame object has no attribute multiply

Can you please help me with that? Thanks.

In the current version of cuDF, this works as expected. You may be using an older version in which this API was not yet implemented. I recommend upgrading.

import cudf

a = cudf.DataFrame()
a['c1'] = [1, 2]
b = cudf.DataFrame()
b['c1'] = [2, 5]

print(a.multiply(b))
   c1
0   2
1  10
