Use pandas.DataFrame.abs().
import pandas as pd
df = pd.DataFrame(data={'count':[1, -1, 2, -2, 3, -3]})
df['count'] = df['count'].abs()
print(df)
count
#0 1
#1 1
#2 2
#3 2
#4 3
#5 3

For complex inputs, 1.2 + 1j, the absolute value is \(\sqrt{ a^2 + b^2 }\).

Use pandas.DataFrame.abs().
import pandas as pd
df = pd.DataFrame(data={'count':[1, -1, 2, -2, 3, -3]})
df['count'] = df['count'].abs()
print(df)
count

You can call abs() on multiple columns too.
df[['col1', 'col2']] = df[['col1', 'col2']].abs()
or use numpy abs() as well, which interestingly returns a pandas object, not a numpy array:
df['col1'] = np.abs(df['col1'])
On a tangential note, if you get SettingWithCopyWarning when you convert column values into absolute values, that means your dataframe is probably created by filtering another dataframe. Turn on copy-on-write mode to turn it off. See this post for more info.
pd.options.mode.copy_on_write = True
df['count'] = df['count'].abs()
or use assign() to make a copy.
df = df.assign(count=df['count'].abs())
