如何将嵌套字典转换为数据框，然后重塑形状？

Question

转换以下内容：

ndict={'signal': {'ACC': [[0.9553999900817872, -0.22200000286102292, -0.5579999685287476], [0.9257999658584596, -0.2215999960899353, -0.5537999868392944], [0.9082000255584716, -0.21960002183914185, -0.5392000079154968]],'ECG': [[0.02142333984375], [0.02032470703125], [0.0165252685546875], [0.0167083740234375], [0.0116729736328125], [0.0048980712890625]],'RESP': [[-1.14898681640625], [-1.12457275390625], [-1.15203857421875], [-1.15814208984375], [-1.16119384765625], [-1.165771484375], [-1.129150390625], [-1.153564453125], [-1.15203857421875], [-1.21917724609375]],'LABEL': [[0.0], [0.0], [0.0], [0.0], [0.0], [0.0], [0.0], [0.0], [0.0], [0.0], [0.0], [0.0], [0.0], [0.0], [0.0], [0.0], [0.0]]}}

嗨lahsiv，因此您可以先将它们转换为csv格式，方法是：

将熊猫作为pd导入ndict = {'signal'：{'ACC'：[[0.9553999900817872，-0.22200000286102292，-0.5579999685287476]，[0.9257999658584596，-0.2215999960899353，-0.5537999868392944]，[0.9082000255584716，-0.21960002183914185，-0.5392000079154968]] [，ECG： 0.02142333984375]，[0.02032470703125]，[0.0165252685546875]，[0.0167083740234375]，[0.0116729736328125]，[0.0048980712890625]，'RESP'：[[-1.14898681640625]，[-1.12457275390625]，[-1.15203857421875]，[-1.15814208984 -1.16119384765625]，[-1.165771484375]，[-1.129150390625]，[-1.153564453125]，[-1.15203857421875]，[-1.21917724609375]]，“ LABEL”：[[0.0]，[0.0]，[0.0]，[0.0] ，[0.0]，[0.0]，[0.0]，[0.0]，[0.0]，[0.0]，[0.0]，[0.0]，[0.0]，[0.0]，[0.0]，[0.0]，[ 0.0]]}}
