这个错误是由于`plt.show()`函数的调用方式不正确导致的。`plt.show()`函数不需要传入参数，它会自动显示当前所有的绘图结果。您可以将代码修改为以下形式：

from matplotlib import pyplot as plt

# 绘制ECG信号，并在一张图片上展示多个画布
fig = plt.figure(figsize=(20, 10))
for i in range(10):
    ax = fig.add_subplot(2, 5, i+1)
    ax.plot(ecg_signal[i])
    ax.set_title(f'ECG Signal {i+1}')
plt.show()

这里的`plt.show()`函数不需要传入参数，它会显示`fig`中的所有画布。如果您需要在多个画布中显示多个信号，可以使用`fig.add_subplot()`函数来创建子画布，并在每个子画布上绘制对应的信号。
