Minor requirement conflict on tqdm

[widiba03304]

There is a minor requirement conflict on tqdm.

Huggingface datasets requires tqdm version to be tqdm>=4.62.1 https://github.com/kingoflolz/mesh-transformer-jax/blob/e84de89465b8526784ab77804864fc3d22fde28c/requirements.txt#L2

The conflict is caused by:
    The user requested tqdm~=4.45.0
    datasets 1.15.1 depends on tqdm>=4.62.1

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict
