Python Plotly express x axis values

Question

I have been trying to create a graph using plotly express. however, I haven't been able to put the values for the x axis correctly. Here is the data frame I am using:

I need to plot 'Mean Train Score' vs ' Hidden Layer Size' keeping 'Activation Function' and 'Learning Rate' Constant, and this is the code I am using to plot it:

[1] df['No. of Neurons in Two Hidden Layers'] = [t[0] for t in 
                                                zip(df['Hidden Layer Size'])]


[2] df['Alpha, Activation'] = [f'{alpha} {activation}' for alpha, activation in 
                              zip(df['Learning Rate'], df2['Activation Function'])]

[3] fig = px.line(df, x='No. of Neurons in Two Hidden Layers', y="Mean Train 
               Score", color='Alpha, Activation', symbol = 'Alpha, Activation', title 
               = 'Mean Train Score vs. No. of Hidden Layer Size' )
    fig.update_layout(
    title = {
             'y':0.9,
             'x':0.5,
             'xanchor': 'center',
             'yanchor': 'top'
            })
    fig.show()

I cannot display both of the values for the 'Hidden Layer Size' column on the x axis

I need each value of 'Mean Train Score' to have its corresponding Hidden Layer value as (#,#).

What can I do?
