이 에러 어떻게 해결해야하나요..??

import matplotlib.pyplot as plt
import numpy as np

data = np.loadtxt('20221101_20221130_download.csv',dtype=str,delimiter=';',skiprows=1)

temp = data[:,4].asypte(float)
pm25 = data[:,2].astype(float)
co2 = data[:,3].astype(float)
rh = data[:,6].astype(float)

tiime = np.arrange(288) *5./60.

fig, axs = plt.subplots(2,2)

n = 0
ax = axs.flat[n]
ax.scatter(temp,pm25,c=time)
ax.set_xlabel('temperature ($^\circ$C)')
ax.set_ylabel('PM$_{2.5}$ (ug/m3)')

n += 1
ax = axs.flat[n]
ax.scatter(temp,c02,c=time)
ax.set_xlabel('temperature ($^\circ$C)')
ax.set_ylabel('CO$_2$ (ppm)')

n += 1
ax = axs.flat[n]
ax.scatter(temp,rh,c=time)
ax.set_xlabel('temperature ($^\circ$C)')
ax.set_ylabel('RH (%)')

n = 0
ax = axs.flat[n]
ax.scatter(c02,RH,c=time)
ax.set_xlabel('CO$_2$ (ppm)')
ax.set_ylabel('RH (%)')

fig.tight_layout()
plt.show()

참고로 csv 파일 일부는 이렇습니다.
time,PM10(ug/m3),PM2.5(ug/m3),CO2(ppm),VOC(ppb),Temperature,RH(%),noise(dB),CAI(cici)
