python - RuntimeError: Attempted to use a closed Session in tflearn -


i want train model tflearn, error showed above. here training loop: btw splitted training inputs in seperate numpy files

for in range(epochs):     file in filess:          file = np.load(file)         x = []         y = []         a, b in file:             x.append(a)             y.append(b[0])         x = np.array(x).reshape(-1,width,height,1)         sd in range(len(y)):             idx = genres.index(y[sd])             y[sd] = idx         print(y)         y = np.array(y)         try:             model.load(model_name)         except:             print("no model")          model.fit({'input': x}, {'targets': y}, n_epoch=1,  snapshot_step=500, show_metric=true, run_id=model_name)          model.save(model_name)`

here full error message:
