Question

我已经使用import numpy as np import matplotlib.pyplot as plt t = np.arange(0.0, 2.0, 0.01) s = 1 + np.sin(2*np.pi*t) plt.plot(t, s) plt.xlabel('time (s)') plt.ylabel('voltage (mV)') plt.title('About as simple as it gets, folks') plt.grid(True) plt.savefig("test.png") plt.show()命令将matplotlib下载到了Mac Book Pro。

我尝试运行以下代码

runfile('/Users/giridhar/PycharmProjects/numpy/matpotlib1.py', wdir='/Users/giridhar/PycharmProjects/numpy')
Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "/Applications/PyCharm CE.app/Contents/plugins/python-ce/helpers/pydev/_pydev_bundle/pydev_umd.py", line 197, in runfile
    pydev_imports.execfile(filename, global_vars, local_vars)  # execute the script
  File "/Applications/PyCharm CE.app/Contents/plugins/python-ce/helpers/pydev/_pydev_imps/_pydev_execfile.py", line 11, in execfile
    stream = tokenize.open(file)  # @UndefinedVariable
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/tokenize.py", line 392, in open
    buffer = _builtin_open(filename, 'rb')
FileNotFoundError: [Errno 2] No such file or directory: '/Users/giridhar/PycharmProjects/numpy/matpotlib1.py'

我收到此错误

Invalid Schema Content

能否让我知道我在犯什么错误？
