你好，之前的错误是因为numpy的版本错误，纠正版本后，仍然有报错，如下：（一定要安装cuda库吗？我的机器是云上虚拟机，没有cuda设备） 2023-02-11 05:01:10.764147: E tensorflow/compiler/xla/stream_executor/cuda/cuda_driver.cc:267] failed call to cuInit: CUDA_ERROR_NO_DEVICE: no CUDA-capable device is detected 2023-02-11 05:01:10.764322: I tensorflow/compiler/xla/stream_executor/cuda/cuda_diagnostics.cc:156] kernel driver does not appear to be running on this host (qinh154): /proc/driver/nvidia/version does not exist numpy() is only available when eager execution is enabled.
