इनपुट की जाँच करते समय त्रुटि: अपेक्षित घने_203_इनपुट का आकार (1202,) होना चाहिए, लेकिन आकार (1,) के साथ सरणी मिली

मैंने एक बहुत ही सरल तंत्रिका नेटवर्क बनाया है, जो सुदृढीकरण सीखने के लिए है। हालाँकि, मैं कुछ भी भविष्यवाणी नहीं कर सकता क्योंकि भविष्यवाणी करने का प्रयास करते समय मुझे एक त्रुटि मिलती है।

प्रश्न में त्रुटि:

इनपुट की जाँच करते समय त्रुटि: अपेक्षित घने_203_इनपुट का आकार (1202,) होना चाहिए, लेकिन आकार (1,) के साथ सरणी मिली

सवालों में मॉडल:

 def _build_compile_model(self):
    model = Sequential()
    model.add(Dense(300, activation='relu', input_dim=1202))
    model.add(Dense(300, activation='relu'))
    model.add(Dense(200, activation='relu'))
    model.add(Dense(self._action_size, activation='softmax'))

    model.compile(loss='mse', optimizer=self._optimizer)
    return model

मॉडल को कॉल करते समय त्रुटि होती है। भविष्यवाणी (राज्य) जहां राज्य आकार की एक सरणी है (1202, 1)।

पूर्ण त्रुटि संदेश है
