如何从类似输入字符串的列表中获取名称？

Question

我有一份清单如下

[<tf.Variable 'resnet_v1_101/conv1/weights:0' shape=(7, 7, 3, 64) dtype=float32_ref>, <tf.Variable 'resnet_v1_101/conv1/BatchNorm/beta:0' shape=(64,) dtype=float32_ref>, <tf.Variable 'resnet_v1_101/conv1/BatchNorm/gamma:0' shape=(64,) dtype=float32_ref>, <tf.Variable 'resnet_v1_101/conv1/BatchNorm/moving_mean:0' shape=(64,) dtype=float32_ref>, <tf.Variable 'resnet_v1_101/conv1/BatchNorm/moving_variance:0' shape=(64,) dtype=float32_ref>, <tf.Variable 'resnet_v1_101/block1/unit_1/bottleneck_v1/shortcut/weights:0' shape=(1, 1, 64, 256) dtype=float32_ref>, <tf.Variable 'resnet_v1_101/block1/unit_1/bottleneck_v1/shortcut/BatchNorm/beta:0' shape=(256,) dtype=float32_ref>, <tf.Variable 'resnet_v1_101/block1/unit_1/bottleneck_v1/shortcut/BatchNorm/gamma:0' shape=(256,) dtype=float32_ref>, <tf.Variable 'resnet_v1_101/block1/unit_1/bottleneck_v1/shortcut/BatchNorm/moving_mean:0' shape=(256,) dtype=float32_ref>, <tf.Variable 'resnet_v1_101/block1/unit_1/bottleneck_v1/shortcut/BatchNorm/moving_variance:0' shape=(256,) dtype=float32_ref>, <tf.Variable 'resnet_v1_101/block1/unit_1/bottleneck_v1/conv1/weights:0' shape=(1, 1, 64, 64) dtype=float32_ref>, <tf.Variable 'resnet_v1_101/block1/unit_1/bottleneck_v1/conv1/BatchNorm/beta:0' shape=(64,) dtype=float32_ref>, <tf.Variable 'resnet_v1_101/block1/unit_1/bottleneck_v1/conv1/BatchNorm/gamma:0' shape=(64,) dtype=float32_ref>, <tf.Variable 'resnet_v1_101/block1/unit_1/bottleneck_v1/conv1/BatchNorm/moving_mean:0' shape=(64,) dtype=float32_ref>, <tf.Variable 'resnet_v1_101/block1/unit_1/bottleneck_v1/conv1/BatchNorm/moving_variance:0' shape=(64,) dtype=float32_ref>]

我想获取列表中存储BatchNorm的所有名称，并将其存储在新列表中，而不重复。名称将被剪切，直到批处理结束。例如 输入

'resnet_v1_101/block1/unit_1/bottleneck_v1/conv1/BatchNorm/moving_mean

输出

'resnet_v1_101/block1/unit_1/bottleneck_v1/conv1/BatchNorm'

我在新列表中的期望值是

['resnet_v1_101/conv1/BatchNorm','resnet_v1_101/block1/unit_1/bottleneck_v1/shortcut/BatchNorm','resnet_v1_101/block1/unit_1/bottleneck_v1/conv1/BatchNorm']
