Tensorboard problem : failed to communicate with data server

Question

I am using tensorboard 2.8.0 with tensorflow version 2.7.0 on a oracle virtual machine.

As I try to run tensorboard using "tensorboard --logdir= ./", I get the following errors:

2022-03-02 13:36:40.878355: W tensorflow/stream_executor/platform/default/dso_loader.cc:64] Could not load dynamic library 'libcudart.so.11.0'; dlerror: libcudart.so.11.0: cannot open shared object file: No such file or directory 2022-03-02 13:36:40.878459: I tensorflow/stream_executor/cuda/cudart_stub.cc:29] Ignore above cudart dlerror if you do not have a GPU set up on your machine. 2022-03-02 13:36:42.103012: W tensorflow/stream_executor/platform/default/dso_loader.cc:64] Could not load dynamic library 'libcuda.so.1'; dlerror: libcuda.so.1: cannot open shared object file: No such file or directory 2022-03-02 13:36:42.103101: W tensorflow/stream_executor/cuda/cuda_driver.cc:269] failed call to cuInit: UNKNOWN ERROR (303) 2022-03-02 13:36:42.103143: I tensorflow/stream_executor/cuda/cuda_diagnostics.cc:156] kernel driver does not appear to be running on this host (RAID-VM): /proc/driver/nvidia/version does not exist W0302 13:36:42.517463 140093920405312 server_ingester.py:187] Failed to communicate with data server at localhost:35561: <_InactiveRpcError of RPC that terminated with: status = StatusCode.UNAVAILABLE details = "failed to connect to all addresses" debug_error_string = "{"created":"@1646224602.517032503","description":"Failed to pick subchannel","file":"src/core/ext/filters/client_channel/client_channel.cc","file_line":3093,"referenced_errors":[{"created":"@1646224602.517030941","description":"failed to connect to all addresses","file":"src/core/lib/transport/error_utils.cc","file_line":163,"grpc_status":14}]}"

My local virtual machine is configured with my universities vpn, so that from the virtual machine we have access to the internet.

I have run diagnostic_tensorboard.py but do not receive any error messages.

Can someone help me?
