jupyter notebook - TypeError: Neither the `x` nor `y` variable appears to be numeric

Question

I am trying to generate a boxplot using seaborn, on jupyter notebook, but I receive this error. This is the simulator along with the jupyter notebook file and results: https://github.com/netreconlab/smartcomp19

Part of the code which results in error:

ax = sns.boxplot(x=['Sensor u2192 Bus','Bus u2192 Gateway'], y=[np.array(ons_tbs)/60, np.array(ons_tbg)/60])
#ax.set_title('(e)');
ax.set_ylabel('Delay (Minutes)')
ax.figure.set_size_inches((10,10))
ax.set_title("Delays for on-route packets")
ax.figure.savefig('e.png', dpi=300)

print("Sensor->Bus 
Mean: {0}, Median: {1}".format(np.mean(ons_tbs)/60, np.median(ons_tbs)/60))
print("Bus->Gateway 
Mean: {0}, Median: {1}".format(np.mean(ons_tbg)/60, np.median(ons_tbg)/60))

TypeError                                 Traceback (most recent call last)

TypeError: Neither the `x` nor `y` variable appears to be numeric.

I don't know how to solve this issue, any suggestion would help. Thank you!
